I think that if you are able to cut one down and grind in get the proper taper on the end that you cut, it could work out.
Do a search on wastegate springs. I posted the length of a .7 bar spring in one of those threads. With a little interpolation you could arrive at the length of an .5 bar spring.
A shorter spring will exert less force when captured in the wastegate than a longer one. If you have a mechanical boost gage you can check your work. If you don't have one, time to install one before you experiment.
Good luck and be sure to post your results for the naysayers
