I think no.
The IMC hours does not count towards your IR, so nothing gained there.
You will get some kind of experience, which could help you thru the IR, but with 50/55 hours IR training you should be able to do it just fine.
If I had extra money to spend before starting my ME-IR, I might use them on extra MEP hours with instructor or solo/renting. The minimum hours for the MEP are very low, and I struggled with that part.
But then again everybody is different. Maybe others have better suggestions
