Yeah you can. There are so many variables you should price it up yourself based on where you are prepared to travel to etc.. Price up PPL, night, 50 hours cross country, CBIR, MEP, MEIR add-on, 15 hour SE CPL and whatever extra hours you need to meet 200/100. Add in the cost of ATPLs and exams and flight tests. Bear in mind it may be cheaper to join a syndicate for hour building etc.
