An interesting bore stroke question...

So why isn't it done?

Not quite getting the potential for comparison

I can't even work out how an AR set up could even work in a springer, plus it would make it look like a Air Arms Combat

I'm saying, if you look at the ICS M4 airsoft rifle, it's obviously an AR platform... the bottom half has the motor, trigger, gearbox, and the upper half holds the spring, piston and compression tube all in a handy clamshell package. The rifle splits open same as an AR, but the upper gearbox as they call it, comes out and can be swapped over with ones containing heavier springs, larger bores etc.

As for why isn't it done? Simple. Because nobody has done it yet ��

It's a bit of a crude drawing, but I'm thinking something like this

Ahh, got you, not quite AR but anyway. Thing is, as I believe someone pointed out already - it's not at all necessary to go down that route with an underlever. (Engineering wise, needing to make everything super stiff would mean the sketched design would be ludicrously heavy and bulky) Everything is already modular today, no changes needed. You can swap out a compression tube and piston of the TX/HW type with one with thicker walls and shorter/longer latch rod. Voila, reduced bore / stroke or vice versa.
