go for it mate - sounds similar to what I'm doing. Just watch out for the 3 year time limit on doing the ATPL theory exams until finishing your CPL/IR/MCC. If I understand the regs correctly, you would have to redo them if you couldn't finish by then.
Sounds like you should be able to finance it all in 3 years though (always good advice to have a degree), by which time (we all hope) someone will be hiring again.
Good luck
