variable speed pump idea

  1. need input on the idea of replacing the motor on an old Ampmaster pump with a variable speed 3 phase motor and a pc compatible controller . House already has 3ph service btw. would make for a great closed loop/wave making system pump!
    Only problem is I can not find a 3ph motor with the correct frame size and shaft threads. I think I will get a stub shaft made just like the old 1ph motor and use shaft couplings to hook the 2 together.
    Anybody see this as totally wack?
