To all this great advice I would add that to answer the OP's question would require a determination of the total potential market for such a product at a potential price point. I'm not sure that the folks on this board represent the target market as many of us are more interested in building than just flying. Folks with the funds to buy expensive kits and parts may not be reading this.
Given what we already know about the total market (Velocity and Cozy and all the variants of EZ(e)s, etc I would say the market is not too big (fancy marketing terms) and would be unlikely to support the kind of capital intensive project you are contemplating. I would be hesitant to enter such a market unless the potential buyers was measured in hundreds or thousands, not tens and twenties. Talk to your banker to see what I mean.
From my recent visit to Sun and Fun I think there is a lot more interest out there in new composite LSA aircraft, where people are paying $75-$125K for inexpensive to operate, lower performance, no Medical required craft. Maybe you could subcontract for some of that work?
I for one would love to buy a Berkut kit today, but I, like so many others, can't afford one.
Best of luck in your endeavors.
