I want to make a flat pattern or unbend this part but Pro/E won't let me. Is it possible to unbend a sketch like the one shown?

The Pro|E sheetmetal unbend features only work on standard press brake kind of bends. in other words a single direction of material deformation. Things that require multiple directions of deformation, like what you have shown, cannot be 'unbent'. You might try a form feature and the flatten form tool, although I've no experience with it myself. Doug Schaefer
That and I've never seen Pro be able to hand a bend without a straight surface to use as the unbend surface. I could be wrong or I may have just given up too quickly in the past, but that's my experience.
