Pacer benefits: It has a lighter fuselage than a Bearhawk
Bearhawk benefits: It has a less draggy wing than a Pacer. There is one strut, no jury struts, and the airfoil is less draggy.
Unfortunately, I have already looked into this and the spars are different distances from each other. If you didn’t want to rework the spar attach points (and much of the structure around the cabin) I think the best thing to do would be to build a Bearhawk companion. It has a lighter fuselage than the 4-place, but the same wing (longer than the short wing) with only one strut. If you wanted four seats (I would), you would need to figure out how to add back seats to the Companion, since that’s not its selling point. It’s experimental, so you can figure out your own back seats (or just copy the Pacer’s since it works). It’s got the useful load for children in the back, etc.
Since we are talking experimental already, your other option is to clean up the fabric wing as much as you can. You could get Badland’s leading edge cuff, clean up with fairings, get the different airfoil ribs, and stay with the short wing if you want to be fast (ish); or extend the wing if you don’t care about the jury struts.
This is what I’ve been thinking about on this subject.
