For one, putting the tank in the stock complicates the design and disassembly of the gun because it means the stock is in the way of the internals sliding out freely from the back. It's easy enough to have the stock unscrew or lift out in this situation but it's much more complicated if an airline has to be routed back there.
I think a bigger reason is that a lot of users simply aren't going to want to use the stock. CAR-style stocks aren't designed with paintball masks in mind, and it's nearly impossible to aim down the sights when using this kind of stock because you can't get your cheek close enough, necessitating the use of a very tall sight riser for clearance.
Using the tank coming off the grip as the stock is a far more ergonomic setup for players wanting to sight down the top of the gun without taking their mask off.
