Is it even possible to replace a cv boot on this type of shaft?

Yes, I got a universal boot now made of rubber and stretchable, but I wanted to remove the joint, so I can clean it better. Haynes for Renault 5 doesn't mention anything regarding difficulty taking it out, it just says to pry out one of the star arms retainer . If it's hard to take it out I'll just clean it from the outside.
