Easily doable.
Wait, what kind of construction? "laminated bow" covers a lot of ground.
I've gone more extreme than that with a bamboo backed osage core. 64" ntn, 14" handle piece glued on, mild d/r, and 70# @ 28". I make such bows trapped to the back, and fully radiused on the belly and into the dips, and handle... it flows. Flow helps 'merge' things.
Also made 'laminated bow' trilams in the shapes of hybrids and recurves over 60# @ 28" as short as 58" ntn with 9" glued on handles that encompassed the dips, flares, and handle... with no power lams.
Basically what I'm saying is, what you want to do is doable. This stuff is all relevant. Our ability to push limits isn't all about the ability of the woods, preps, glues, and such... our abilities come into play as well, and we don't know yours.
I say, push yours(you and the wood) limits accordingly.
Heck, I just realized, you didn't even mention what kind of wood you were gonna use :^)
