You'll have enough width for that drawweight.
However, the drawlength bothers me a bit. Why do you want to draw it to 32"? Are you trying to go for a warbow style draw? Or are you 7 feet tall? Most archers draw 28" maybe up to 29". And with your drawweight, I don't think you're after a warbow style shooting style, are you? Either way, with that drawlength, I think you should try to make the bow 76" tall, or if your stave is 74", you might consider lowering your drawlength an inch.
A tip for a hickory longbow: leave the belly flat, but crown the back a bit.
