Try doing past papers to pass. I roughly spent 100 hours on reading the material and doing the pass papers. Don’t give yourself too much presure. The passing mark is crystal clear at 50% and that’s all you need.
If you can’t make it in first attempt, you can try again in another six months.
All the best and let me know if you need further help.

Its not appropriate to consider the overlap since ACCA papers are based on essay type but CFA level 1/2 are MC type.
Even if there is overlap for the mentioned papers, you still got to study for other papers. So I suggest at least 100 hours per paper to achieve a passing mark of 50 and thats all you need.
