OP--if you want to make the change to floating it won't take all that long in my experience.
I was a "planter" when I started lessons with a classically trained teacher. He highly encouraged me to float (his theory being the ring finger can't move freely if the pinky is planted) and since I was paying him I agreed to try it.
I would say it felt natural within a couple of weeks. But I was not very far along as a finger picker when I made the change, less than a year. I'm glad I did it, but that is not to disparage anyone who plants (MJH, Tommy E, Stefan Grossman and Woody Mann just off the top of my head!).
I can still plant if I want to but it feels kind of strange, unless I'm planting the side of my palm on country blues type stuff.
I agree with all those who say whatever works, works. For most of us the perfect is the enemy of good
