Lengthening the center spars would REDUCE the load on the WAFs, not increase it, because now they are carrying less load, as there's less wing out past there. Think of the load they'd carry if you put the WAFs out a foot from the tip, and it becomes obvious. The center spar is stronger than the outer spars, so there's another reason it won't hurt anything. The downside would be getting it on a trailer and down the road, as the airplane would be wider, but that's probably not a biggie, since highway transport is a pretty rare occurance with a KR. I think the main spars are 84" long right now, so if you went to 94" (which would leave a little room for WAFs to protrude) you'd still be "street legal", but I wouldn't let that dictate the length. It should also be mentioned that carrying fuel in the outer wings is practically a free lunch for the WAFs, unless you tend to land really hard. But I like mine in the stub wings, so there are no fuel connections when disconnecting the wings, but then that's not something you'd have to do very often either.
