Ideas/Advice for my Roof Rebuild
Call an architect. Seriously call one. Let them know what you'd like to do. Ask for some ideas. They can take the structure, age, other home styles in the area and give you a slew of options that are suitable and sound.

And it shouldn't cost that must either. They can suggest and sketch out rather quickly the style based on many factors including load weight, pitch, roof material you're going to use and more. There's modern materials, ways to get light in, sun roofs, venting, insulation that all factor in to a design. 

A local architect is also in the know on building codes etc.

Looking around for ideas it's one thing but if you're serious about replacing the roof, an architect is the one to consult.
