You could do it in a lot less than that. You don't need a miracle, you just need an ATO that is on board and a plan. My suggestion:
1) Forget about MEP
2) Forget about MEIR
3) Get a CBIR (40 hours) and CPL (15 hours)
You have 55 hours to fly in 49 days, that's less than 1.2 hours per day. Aim to fly 1.5-2 hour training flights twice per day and you'll finish the syllabus even with half of those days unflyable. It's summer and you're IR training so weather is less of a factor. You won't go over hours because IR flying is very simple. Use a free sim to train yourself on holds, chair fly a lot, memorise the checklists and you're good to go.
Get off your ass and start calling ATOs. Tell them you want either an IRR or CBIR, you've got cash, you want to fly twice a day and you want to start TOMORROW.
Don't even consider not attempting both check rides, not having valid ATPL passes will cause you a world of pain come upgrade time.
Fly it all the way into the crash 😜
