"Can you" -- yes. In much the same way that you can put bald tires on your car and drive in the rain, you can certainly do this.
As Davide Andrea mentions in his answer, what you should do for a product is use a 3S battery management system. If, however, you're going to use model airplane rules to save cost and expense, you should use model airplane rules to build up your battery pack: use the same cells from the same manufacturer, then use a high-quality balancing charger -- and always store the pack somewhere that it can catch fire and burn off without burning down your house or shop.
If you're absolutely broke -- and you can store the cells where they won't catch other stuff on fire -- then you can probably get away with doing this if you use a balancing charger, if you're not demanding the maximum possible current from the cells, if you check the pack regularly for balance, and if you're prepared to dispose of it properly when it starts showing signs of distress.
Note that all of the above "ifs" are what you should do anyway if you're the battery management system for an airborne pack; you just need to be more careful than usual. In particular, start using the pack gradually, with each run taking more charge than the last. Check the cell balance carefully (your charger should do this, and if it doesn't you should make sure to have a battery checker). You'll see that the cylindrical cell will either be weaker or stronger than the two pouch cells -- you need to figure out how long and hard you can run your gizmo without dropping any one cell's resting voltage below 3.2V (higher is better) at the end of a run.
Note that when you use the cells this way you must expect them to be a wear item. Serious model airplane folks buy spare packs, monitor them for health, and dispose of them properly when they die.
Frankly, unless this is a one-time thing that you only expect to get a couple of dozen uses out of, I recommend that you find an actual hobby supplier (Horizon, A-main, ThunderPower in the US, or your local hobby shop). Then learn how to take care of battery packs (search the web -- "model airplane battery care" may be a good start). Then buy at least two packs and a good charger. Then pay attention, and don't burn your house down.

We have briefly introduced the pouch cell (also called soft pack) battery in our first video, and this video will introduce its features in detail for you.
One of the differences between pouch cell batteries and other batteries is the material of the casing. Cylindrical batteries have a hard casing, which are made of nickel and steel or aluminum alloy.
A pouch cell on the other hand consists of many types of layers to form a multilayer film consisting of an outer layer, middle layer, and an inner layer.Outer layer consists of nylon, middle layer contains an aluminum foil, and in the inner layer - a heat sealing layer, which allows for better heat dissipation.
There are four distinct advantages for a pouch cell compared to cylindrical batteries.
Advantage 1: They’re
Safer
If you are looking for more details, kindly visit sinopoly.
Firstly, it has a very high barrier property; secondly, it has a good heat sealing property; thirdly, the material is resistant to electrolyte and strong acid corrosion; it also has good ductility, flexibility and mechanical strength, and this advantage makes the pouch cell battery safer. When a safety hazard occurs, the pouch cell battery will only swell and crack at most. Unlike the steel shell battery where a sudden explosion phenomenon might occur.
Advantage 2:
Better space utilization
The pouch cell’s exterior is flexible thus making the most efficient use of space and can reach a packaging efficiency of 90-95%, which is unreachable by other types of casing. The flexibility will allow the external case to form to the battery, rather than the other way around.
Advantage 3:
Higher energy density
Eliminating the metal case can reduce weight. In terms of weight, a pouch cell battery of equivalent capacity is 40% lighter than a nickel-steel cased lithium battery and 20% lighter than an aluminum-cased battery. In terms of energy density, pouch cell batteries of the same size are usually 10-15% higher than steel-cased batteries and 5-10% higher than aluminum-cased batteries. Grepow's pouch cell batteries can reach a single energy density of 280Watt hours per kg or more, which is much higher than most of the hard-shell lithium batteries on the market.
Advantage 4:
Customizable
Pouch cell batteries can be custom designed according to the specific requests of the customer. With their soft exterior and ability to be reshaped and sized, custom designed packs can be formed to meet all challenges. Cylindrical batteries adhere to only a handful of sizes, the most well known sizes are CR123, and 18650. On the other hand, pouch cells are not as limited and there are thousands of sizes available on markets today.
