Well, if you're looking for a warbird trainer that sort of doubles as a sport model then I'd say you'll get a lot of results doing what you're planning. It's still an odd choice of model given the SE's original intended flying style but what the hey. Have at 'er and all the best.

Although.... if I was looking for a warbird trainer I think I'd look at doing a sort of "Stand Way Off and Squint Scale" (SWOSS ) model that uses a more or less warbird layout. Picking a sport or pattern sort of model and adding a big scale sort of looking fuselage wouldn't be that hard to do. Something like a SWOSS Skyraider would actually be a bit cool. And the fuselage would be big enough to stick a camera into. Meh... just a thought.

A few years back a local guy had a Sig Kadet that he'd built up with a lot of experimental metal work details that he wanted to use on a quarter scale model later on. The Kadet came out at 10 lbs... [X(] so he added an extra rib bay on each side. It didn't help much, I think I heard that he got something like 10 to 20 flights out of it before the odds called in the debt. But something similar but lighter and with gobs of washout and perhaps the Selig 8035 airfoil to help out would be an interesting heavy trainer.
