Well, since you asked.
If you can cosy up to one of the many competent machinists on this forum, toss the idea of a bit of DIY, to replace the Vixen R&P with the F/T unit, something like the FT2015 or maybe (if there is enough inside clearance) the FT2020. Where you will need the machinist is to machine a face-plate to accept the F/T and attach to the rear cell, with those collimation screws you mention.
But, always a gotcha of course, you will also need this machinist to fit the filed flattener lens system onto the front of the F/T draw-tube, at the correct distance.
Not rocket science, and given a decent lathe, and machinist, and a bit of drive it can and would be simple enough.
Of course you could just wimp out, and tweak slightly the bog standard unit, and fit it with something like a RoboFocus, others have and are quite happy.
