26" no problem. In my novice opinion that is. You could make it a bend in the handle bow and if the whole thing was working, and desinged and tillered good, you could easily do it.
From what I understand, you want enough limb working as twice your draw. So for my 29" draw, I need 58" of working bow. Throw in 4" of stiffness in handle, and 60-62" bend in the handle bow. Or 58" of limb plus 4" of handle plus 4" of fades, and need 66" Nock to nock bow for a stiff handled bow. Its working out for me.
