I am in a similar scenario, and have read these boards with interest and taken advice from those with experience.
For what it is worth, the best advice I have received seems to be that the PPL, distance learning for the ATPL, hour building and even the CPL at a push can all be done part time whilst working.
However, the instrument rating is by far the toughest part and should absolutely be done in one hit if possible. This will mean taking 8-12 weeks out of work, but I have been told certainly worth it.
Best of luck, and hopefully in a few years when we have all the licences there will be some jobs around that aren't ring fenced for integrated cadets or those that have gone through p2f!
