If that is how you want your house rules, sure.Using LBB2 rules its pretty easy, since smallcraft take up no extra volume in ships.
Just extrapolate from the thirty ton module carrier.
...
Lots of potential, all the rules that are needed are already there.
The cutter module is external, and drive performance is recalculated when dropped, i.e. the volume of the craft changes...
Not carrying a module affects the structural integrity of the craft.
Fuel in modules can presumably be used directly, fuel in carried small craft can't.
Cutter modules don't work like carried small craft, at least by default. By RAW there are no rules for how generic modules work, or how to design them.
