Using extruder motor as 4th axis

I am currently working with a hobbyist robotic arm (uArm Swift Pro) which runs a modified version of Marlin 3D printing firmware. The arm can be used as a 3D printer as well thus it has an extruder motor. I am not using it as a 3D printer, instead…

Can I repurpose most of the components of this Prusa clone for a Delta?

I have a generic Prusa clone that I'm not using (my primary issue with it is the lack of rigidity in the frame housing as built). Will the motors (ks42sth40-1204a) and controller that come with it be good for a large-ish Kossel? Something no smaller…
