Well, he pretty much came out and said that's what he was going to do.

I considered this when I converted my DJ-20 to single phase, but decided
against as I had no desire to run any additional 3-phase stuff. If I knew I
was going to have 2+ 3-phase machines, I'd think a lot harder about it.

Unfortunately a 3 phase motor requires a 3 phase power source either from
the utility company or from a converter that is driven from single phase.
Rewiring is not an option.

I have done this exact same conversion with my own DJ-20 a few years back.
1. Find a motor. I ended up finding a new one at Farm-n-Fleet for about
$125 IIRC.
2. Decide what you want to do for controls. My jointer has push buttons
for on and off that run on 24V. There is a transformer that steps the input
voltage down to 24V. I could have wired in a new 120V switch, but I decided
to keep the existing controls. While I would like to run this on 240V in
the near future, I currently run it on 120V. This required a new
transformer as the lowest input voltage on the existing one was 200V.
3. Rewire box. I put a picture on a.b.p.w of the control box on my
jointer. Basically, I treated L1 as hot and L2 as neutral. I also
essentially bypassed the heaters. For the wiring, just use white everywhere
and put some tape on the ends to show what color it should have been (just
kidding, Doug...we can only do that here in Chicago).
4. Wire the motor.
That was basically it. I'm no machinery or controls whiz by any means, and
I got this working on the first try, so it must not be too hard. If you
have any questions, I'll attempt to answer them.

Unless you swap the current motor for a single phase one you will need 1 of
the following: A "VFD" electronic device that will take single phase in and
output 3 phase or a RPC- rotary phase converter -a motor and electronics
that will generate the 3rd phase or a static phase converter- electronic
device that will allow you to run a 3 phase motor on single phase power but
will usually reduce the hp rating of the motor.
if you Google VFD or RPC you'll find lots of info on the subject you can
also look at the www.practicalmachinist.com forum for power conversation.
enjoy

One more thing...I interpreted "change the motor" to mean "replace the
motor". If you thought you were going to somehow rewire it for
single-phase, then as Don says, you're out of luck. If you wanted to keep
the motor, then you'll have to do as Andrew suggested.
