I don't see how this can be a problem.
My avia alma mater, Del Sol Aviation, definitely can take anyone from Student Pilot to CFI-I. Now, about 80 hours, that's a good question. I passed Private checkride at 70. However, I observe students who do compressed courses. They come in and start flying almost every day, hogging the leaseback 172, and then one day you can see them switching to Arrow and taking it for 3-hour flights. It is very apparent from looking at the weekly flight schedule. Then one day they disappear without a trace, and you know that another time building CFI was released upon the aviation world
These students definitely use way less calendar time than I did, and probably fewer Hobbs hours, too.
Edit: To the Ron's point above, Del Sol also offers multi in a Cougar, with MEI instructors on staff. But I see almost no takers, which is kinda a pity. Keeping that bird is probably expensive, and every time I rent, I subsidize the FBO's flagship.
