You still have two and a half years, so there's time yet for your IR. With IMC rating and some aeros experience, that would put you above the typical fresh out of school FI, and may help you secure a job. You could even get the Aerobatics restriction removed from your rating straight away and that would definitely appeal to some schools. Also your age might be in your advantage, as a lot of schools are full of guys in their early 20s, it's always good to balance that out.
So if it were me (and once upon a time it was) I would do CPL - FI - work for another year - 18 months and then think about the IR. If you then find yourself instructing at a school which offers the IR you may then get a discount, or be able to fit the training around your instructing.
