I have an "old" "K&D" tool in my historical tools section, that is a hydraulic lifter remover.
It has internal "hooks" and fits into the internal grooves within the lifter that are intended for the retaining clip in the lifter itself.
I haven't tried it on removing the "roller bearing" but would seem to offer hope in that direction.
Honestly, I went through this on an '80s 302 Ford. At some point Ford decided the pin bearing was a better idea then the sintered bronze machined one.
All the pin bearings offer is just this extra grief in removing them when the time comes.
It is a while ago but I do seem to remember using a large drill bit to get the internal sleeve out first and then using a 1/4" or so, cold steel chisel to destroy the rest and take the pieces out one by one?
Whatever you do, don't go back to the roller/pin bearing disaster. Put in one of Marlin's bearings.
