You would be better off getting a better turntable - go up the Rega chain.
So in the meantime buy an Exact and keep the Elys 2 for when you sell the P2 down the road. With the Exact you don't have to worry about arm spacers for VTA.
If you had a P5/Rega Power Supply then it would be worth upgrading the subplatter etc. The Groovetracer mods are very good.
Ideally you would jump to the new generation P6/8.
