My WC Headmate pump is in need of a rebuild and the parts are no longer available anywhere. There’s a rumor that the Raritan PhII pump will bolt right on. Looking for confirmation on this. Not replacing the whole head. Just the pump assembly. Anyone out there done this?

Mark, I think you may have misunderstood the "solution." Maybe that's why it's a rumor. 
What one does in this case is to retain the old BOWL only, and swap the entire base and pump with the LBA, which is the PHII without the bowl. The bowl mounting holes are identical.
I had a W-C and replaced it with an entire PHII. ::: a little differen than your plan, but here's what the switchout looks like start to finish:

Sorry, not true. The PH SuperFlush (current version of the PHII toilet) base assembly mounting bolt pattern is an exact match for Jabsco and other manual toilets, but the PHII pump is not a "plug & play" replacement on any other manual toilet base. Raritan used to offer a PHII "conversion" (lower base and pump assembly without the bowl, seat and lid), but they've apparently discontinued it 'cuz it's no longer available from any retailer. A couple of 'em are still showing it, but they're always "out of stock."
However, as we say in the South, "there's always more than one way to skin a cat." And with some creative digging I just may have found a way that'll work for you: You can buy JUST the pump from a bunch of retailers. Amazon has the best price I could find for it: $220 Amazon.com: Raritan PHII Pump Assembly (Only Complete): Sports & Outdoors
And you can buy JUST the base assembly from this retailer Raritan 1248W Base Assembly for PHII and PHEII Toilets – RAR1248W for another $53...which would bring the total price to only $53 more than you'd pay for a pump if it were plug & play on your headmate base.
It's not the PH SuperFlush base, so there's no guarantee that the mounting bolt pattern will be a match for your HM, but it's no big deal to drill a couple of new holes and fill a couple. And you'll need to buy a pump handle, but those are standard broom handle diameter so you should be able to find a nice piece of aluminum pipe (heavy enough not to kink when you use it) or just a broom handle (paint it white or any color you like) and a bicycle grip to become the handle at any big box or hardware store.

Hi Peggy… So Im also swapping out an old Headmate (broken pump) for a Raritan PHII marine version (not superflush) & it LOOKS as if both the Raritan pump & bowl have mounting bolts on the same centers & pattern as the old headmate base. Because the Raritan base is longer & wound require modification of the wooden base it sits on, I’m thinking I could just leave the Headmate base in place & separately swap in the Raritan bowl & pump. Lot of headache saved. If for some reason the bowl wont fit, it looks like I could just leave the old Headmate bowl on the old base & just swap in the pump. What do you think? I know you said it isn’t made to plug& play, but it sure looks like it would swap right out.
I should have included that you can re-use the HM bowl...all toilet bowls that mount using a 4 bolt pattern are interchangeable. You will need a new bowl gasket to guarantee a leak proof installation. Be careful not to OVER-tighten the mounting bolts...over-tightening will cause the gasket to "pucker" around the bolts, creating a leak. So start with hand tight...flush the toilet. If it leaks, tighten just another quarter turn. Check again...repeat till it no longer leaks.
Btw,, those instructions also should be followed when replacing a joker valve.
