I also have this challenge. At the moment am operating under an Irish EASA licence (in a previous life I flew for a certain low cost airline...and they wanted us to have Irish licences so converted from UK one).
My instrument rating is not current (but intend to renew some time in the next few weeks) so I cannot teach for the IMC Rating or indeed any applied instrument flying until I renew my IR.
I suppose I could resurrect my UK national ATPL as another way to able to instruct for the IMC Rating.
Additionally the IAA cannot put an Aerobatic Rating on my EASA licence for a year or so because they haven't got round to writing that into their licensing rules yet (I think that's what they said!).
Is it just me but I find these changes to licensing absolutely bizarre - have seriously thought about jacking it all in but I still enjoy the flying and feel I have good stuff to pass on.
We seem to spend more time immersed in all this bolleaux rather than what's really important.
