lets just take his first step- what kind of term limits? he could propose a term limit of 50 years, have achieved what he said he'd do, but make no meaningful change.
A middle ground might be to make those the term limits, but require the representatives to not fill that position that 3rd or 4th term, but able to fill other positions and come back later. E.g.
senate (6) -> senate (6) -> congress (2) -> congress (2) -> congress (2) -> senate (6)
senate (6) -> senate (6) -> congress (2) -> senate (6)
I thought it was a contract
