Why xray pulsars?
Millisecond pulsars have shown themselves to be very accurate - wouldn't an
ensemble of those be a better choice?

I think it's an energy/flux density thing. you need a big antenna to
detect the millisecond pulsars.. bigger than will fit on a spacecraft a
few meters on a side. Cassini was huge (4+ meters in diameter, maybe
twice that long), but a lot of spacecraft are much smaller. The vault
on Juno is about a 1 meter cube.
