So, I was thinking about a method to make some calcium from calcium sulfate. First I would displace the calcium by adding sodium carbonate then reduce
the calcium carbonate to calcium. Would this idea work? if so how? Would I need to preform a thermite reaction with magnesium?

Calcium is never going to be easy.
Your choices are reduction with lithium or high temperature electrolysis. Both with an inert atmosphere.
Look up a table of reduction potentials for an indication of how difficult this will be.

I suspect there might be a third option. Calcium salts are more soluble in many aprotic solvents than alkali metal salts. I figure you could try
electrolysis of CaCl2 in propylene carbonate or something like that.
