Bill,
There is already some of those around - look at the Jabiru from down here, it has proper solid wings and fuse, and can carry two and in its base form around the same distance and speeds as C150/152, They were selling for what was about the equivalent of around $50K or slightly less US$.
Just so you know, I am not a fan of the type, though there is one or two models that have potential - but... there is an example for you of an aircraft less the 50% of some of the ones you talking about, and fitted correctly, can pretty much go anywhere - at least here in Oz under our rules (which very similar to yours)
Cheers
