Forced Induction 2006 Corolla T-Sport Compressor

Hi All,
I have a 2006 corolla T-Sport compressor, the problem is the electro/mechanical clutch on the supercharger, requiring replacement. The clutch is not a replacement part at the dealers, so requires the complete supercharger C/W clutch @ £3000.
My question is, can a replacement part be sourced via the manufacturer of the clutch, or
a solid drive be fitted, and a dump valve to control boost pressure which I believe to be 6psi.
or simply welding the clutch and hub together to create a solid drive and fitting a dump valve to control boost.
Your comment's are much appreciated,
Regard's
Steve
