Actually I am interested in upgrading my MK3.9 to MK4. Apparently the only hardware difference between the two models is the installation of two "Precise 0.9° X,Y stepper motors" that can be bought separately as spare parts.

I would like to know if what I plan to do is possible and eventually upgrade later to MK4S with Prusa kit.
