I'm looking into this option myself and in case anyone is curious about then upgrading the SE IR to an ME IR, this was the CAA's response to just that question:
"To upgrade from a SE IR to a ME IR you will need to complete 5 hours of instruction and a skills test on a MEP aircraft. You will then be issued with a IR-SP-ME class/SE rating."
However, the difficulty in passing that skills test after just 5 hours of multi engine time, even with a lot of single engine instrument hours, is a question I don't know the answer to.
