Chosen Solution

I have a 2012 Macbook Pro I am able to buy a 2010 unibody and just change over my logic board is it possible for me to do?

From comparing the technical specs I would say no this isn’t possible. The 2010 has a Mini DisplayPort while the 2012 has a Thunderbolt port instead - this difference in ports would mean that the holes in the housing would not line up with the other logic board so it wouldn’t fit.
