Theorems TD 125 modification


I own a Thorens TD125. It has an SME arm on it. 
I would like to modify it so that the arm lifter mechanism that comes with the stock arm would lift the SME arm. Wondering if anyone has done that. 
Would like to try and buy as much of the stock items as possible and then hook that up to the SME’s raising/lowering mechanism. I’m a machinist so I could make a few things but would like to keep that to a minimum. Any ideas?
