I'd suggest not-too-heavy bangs, and as you've pretty much ruled out any suggestions of short cuts, colors, or layers, the only change left is either a perm or shaving it all off! You have a lot of foehead (as do I), so bangs would emphasize your eyes more, I do think a below-the-chin straight cut would look nice, like a pageboy, but I don't know what you consider "short." And highlights need not be orange if they are done by a professional.
