SCOR Kneesavers (shown here with a speedplay Frog, optional ) moves the pedal outboard with a threaded extender, for such a situation.

only thing to be aware of is it wont take a End of the spindle hex socket pedal .. because the piece is solid where it screws into the crankarm

I recall specially ordered Thru the company Speed play sells a variety of pedal spindle lengths longer , most pedals make just one .
