Yes! That's what I'm doing this season. Same exact plan. I am never going back. The first autos I harvested have been a huge hit with the people I gift it to. Supposedly it's some of their favorite bud ever. So the quality is there. I got 4 ounces of rock hard nugs off 2 plants earlier this summer. The one on the right is like 7 or 8 grams dry.

I have only started doing them this year, but I'm loving being able to see flowers all season. Instead of just waiting for the end of summer.
From what I've seen so far, they will definitely finish outside, but Ive been finishing them under a HLG 260 v2 r-spec in a 2x4 tent. The strains I have will totally work outside, but it would be tough for them to reach their maximum potential not having 24hrs of light and depending entirely on the sun.
With autos, it's almost like a speed run. Your time is so short to maximize yield, that any lost days can mean a serious hit to quality or quantity.
That being said, you CAN definitely do it all outdoors and kill it. You just need to select strains that are good for outdoors and are bred to be the largest plants possible.
Larger plant = longer life = more forgiving if you get a few cloudy days.
Trying to do a 60 day auto like the ones I showed earlier would be tough outside because they arent getting anything near the 24hrs of light they get in the tent.
