At this point maybe they should just do like a Boyd's Pro Varmint base - but with the forend narrowed and shortened and the buttstock being nothing but a 3" tall by 1.25" wide core of material with threaded studs on the top and bottom and back.
Then offer 3D printed adapters that allow users to set LOP, comb height and angle, toe angle, forend length, and so on, using those studs. Buy the base stock and then choose your adapters like interchangeable handgun grips. Offer every base stock with one option for each 3d printed module then sell others at hefty retail prices so guys that really wanted to experiment could order them one at a time. Shape the 3D printed comb right and you could even allow it to be mounted up top then the recoil pad be able to shift higher on the base-stock and have its top mounting screw go into a stud on the 3d printed comb module.
The modules would be lighter than the laminated wood itself, likely.
Like so:
This could be the base stock:

Then add modules:

I'm not a stock designer, so, yes, those are 5-minute efforts in MSpaint.
