I think it can be done in 60 days in summer given ready access to aircraft and instructors, a seven days a week availability from you, and no significant over-run in the hours you need. As IO540 says, you'll need a well-run school, but I think it's possible.
In June 79, in Yorkshire (Leeming to be precise) I flew 44 hours, all VFR, in the Bulldog when I was on RN EFTS. I only flew on 19 days, and never at weekends. The instructor ratio was high, but I was one of a course of twelve, all working at a similar higher work-rate, with no additional resources , so airframes were tight.
