Cox is offering the Pica Waco. The thread here says its really nice. The 1/5 scale has about 6 foot wingspan.
Or, the GP Stearman and the PT17 both have 6 foot wingspans. I am doing a Stearman this winter.........be advised it has some warts,ie: bad wrinkled covering, hinge slots miscut, shipping damage like cracked cowl and wing braces. And some pieces are mislabled so the top wing doesn't fit till you get that one figured out. And the plans are wrong on the aileron linkage layout. If I had it to do over I'd buy the Waco for about the same money.

The GP Super Stearman is on my "next purchase" list. I just bought their Giant Aeromaster for my G62 Lite (thanks, Ralph).
The Super Stearman (or the military version, if you please) is designed for a 1.20 four-stroke, or so I believe. I'm thinking of installing my Saito R3 1.70 in the nose. That might make a nice home for said engine.
