I got so busy that I never had a chance to follow up on this.
I ended up buying a 5hp, 3 phase Unisaw at auction for a pretty good price. After a bit of researching, I ended up with a Hitachi VFD bought from Wolf Automation (https://www.wolfautomation.com/vfd-3hp-230v-single-phase-12a/) The VFD is advertised as 3hp, but spec'ed at 12a, which is the FLA of the motor on my Unisaw.
Wiring power to the VFD and from the VFD to the motor was cake. Figuring out how to re-use the power switch to start and stop the motor took a little more time, but was pretty simple once I understood the basics of the switch type.
So far, the saw has been humming along beautifully. There is a bit of a VFD whine that I think I might be able to tune out, but it's not bad enough that I've bothered with looking in to it.
