Would there be interest in a dodge TBI setup made for our cars?

on a 1bbl /6, is it as basic as it would be for the v8? (adapter plate and 1bbl sized TBI unit being probably the only differences)

I haven't tried it, but I've thought about it (even in terms of two 1bbl TBI units on an Offenhauser twin-carb slant-6 intake) so I think so, yes.
