Sam; interesting proposition and it has come up at various times in the past, here and elsewhere. In my opinion, the KR was conceived as an economical personal hotrod, simple and light, for personal recreational aviation. In the case of the KR1, it's exactly that. When it widened to the stock KR2, just look at photos of how tightly the pilot and passenger are stuffed into the cockpit (there is an excellent overhead air-to-air shot of that "two goldfish in a very small bowl" arrangement somewhere in the KR Gathering writeups on KRNet but I don't remember which event). Different canopies have improved the headroom situation for some, but it's still tight for two. I think if you're looking for a 4-place, start with a 4-place or you'll spend more time overcoming design revisions and workarounds trying to make a sardine can into a tuna can.
Don't get me wrong... it can be done and many other designs have made that transition and some are very elegant examples. Nat Puffer's Cozy Mk 4 adaptation of the Rutan Long EZ is one that comes to mind.
