Looking at the pretty good choice of 2-seaters from various European manufacturers, many on Permit but some on a CofA, most of which can run circles (literally) around a C150/152, I don't think there would be a market for it outside the flight training industry, and most of that market has barely enough money to pay this month's rent never mind look at a new aircraft.
There is no copyright on the design, any patents would have expired many years ago, yet no aircraft designer has chosen to produce a C15x replica.
