C.Edwards,
Do you make kits now? If not, I would suspect getting into the business would be hard. It has been a long time since I flew IMAC so I don't know all the trends but it seems to me that if someone is serious enough about IMAC to build a quality plane they more often then not build a 40% plane.
My suggestion is that if you want something different, have ideas for something that is better, or just don't like the kits available, build one for yourself and see the reaction and interest you get. Do it for yourself and your own enjoyment and if it turns into something that makes you some money then that is just a benefit.
