If what I’ve heard is correct, you end up with 2 hp. Might not be a bad way to go if you re ok with 2 hp.

What you have heard is not correct. You do not lose any HP with a VFD – a 3hp motor will remain a 3hp motor.
What you heard IS correct for a static phase converter (SPC), which basically just runs your three phase motor on 2 legs of the three – hence the ~1/3rd loss in power (along with other problems).
