I think wildwasser makes an inflatable outrigger, but I'm guessing you did mean outfitting.
If you had hip pads, use heat to loosen the glue. Assuming she's smaller, just glue shims inbetween the old ones and the boat. Tape 'em first to see what works.
Try stuffing towels or newspaper in a plastic bag to experiment with what her feet will need. Dial it in that way, then make better ones out of mini-cell foam.
