It wouldn't matter what they would look like if the limitations were dropped.
Last time I looked, most "2 metre" airframes were actually quite a way off taking advantage of the full 2 metres (maybe it is weight related though)
I think that if the limitations were lifted there would be a lot of threads telling people how you need to use XXX brand of engine and a bigger plane - just like the IMAC scene seems to have degenerated into (ok - I am speaking more from experience downunder).
Meanwhile (to the uninitiated) both remain "boring" sports to non competitors.
