I haven't seen Vince's B-25 but from what I saw of the Me-262 it should be good, and beats my idea of taking a set of Mini-Coupe plans rotate the fuselage section with the wing so the wing is on top & go from there. Would be more like a looks good from 200 yards after a bottle or 2 of Mad Dog 2020 than what Vince is doingIt was for sale a while back for $240K. It's probably a bargain considering the time spent building it. Replacing the Hirths with Valach radials would make for a very interesting airplane. Just don't let Valach know what you're doing or they probably won't sell engines to you. Verner quit making their smaller radials and they might have been too big anyway. Another possibility would be to round up four Lawrance radials. They are the right size and put out similar HP to the direct drive Hirths.
