My suggestion is to start your PPL now possibly at a flying club where you can remain a member and study for your ATPL right after that, but take it easy and join flying tours across Europe.
I am not familiar with the requirements to obtain the CB-IR, but if you can do it, get it done as soon as possible and continue flying across Europe with an IR for your hour building with friends. Once the ATPL exams are sorted out you could get your FI rating and finish off with CPL and MEP and ME-IR when things start picking up.
There is no rush and there is all the time to make this enjoyable.
