Depends how long you want to wait. It IS an idle game...
If your warp is 32768 and your total is 47M, your reset should be around 1400. My estimate about your daily money is 100T/h so 2.4qd a day. The last three girls need 773qd. So that would be 320 days base. You will of course level up your money buildings, that might bring you a x2. So 160 days.
But with 47M total bonus, you should be able to somewhat leisurly, depending on your other activities, do one or more stressfull do two resets a day and include two 10 hour filming sessions and one 8h and one 8 or 12h practise for your Ice. Dora is possible too, and if you do only one reset a day even Pantress, but then it thins out with girls you can do two filming and practise sessions. The limit is fake it times. In the 10 hour frame after completing your favorite girl you do as much high level scene unlocking you can fit it and then reset when filming and practise is done. Rinse, repeat.
With only 1400 reset bonus, you can double that in 14-28 days. Quadruple in 28-56 days. Assuming a double, you then would not need 160 days, but 80 + the time needed to double the bonus. Or assuming a x4 it makes 40 days plus the time needed to achieve the x4 (and the money buildings might not be leveled that far up).
As a funny side note: no one told us in school, we would need English, Grammar and Math to calculate ressource allocation in a porn game and post online about it.
If your top girl is not one of the 14 position girls you might overtake your current hit girl someday. But diminishing returns after stamina 200 hurt a lot and your "speed" might be as low as 2k per day, taking 500 days to catch up per 1M current stats.
