How do women's pants fit you? If the idea isn't too horrific to consider... They generally have a shorter waist to crotch distance, I think. (Hips might be too big, though.)

It would be theoretically possible to move the waistband (and pockets) down on a pair of pants, but that would be a lot of work and not cheap to have done.

Perhaps you could buy a pattern for pants, then have a seamster adjust it to your body. Then learn to sew, or have pants/shorts made for you by a friend or professional.
