You only get 22 days holiday a year?! I feel sorry for you!
I'd say it would be near impossible to complete in 2 years, more like 3. Its going to be even more difficult if you've a family as well.
You will have to give up your job for the CPL MEIR stage, as most of the time it is completed in a 2-3 month block; unless your company is will to give you unpaid leave or a gap year.
Nothing is impossible, its never too late to do it (within reason), go for it if you really want it!
I'd recommend you go and see an AME and ensure you can pass a Class 1 medical before you proceed with any training.
