yeah that would make sense - very similar to mineIn theory: What if you connect 4 cells (or whatever BMS you have supports), and when the BMS shuts off charging, remove that one high cell and replace it with a fresh one. Repeat the process each time a cell trips the BMS. Eventually you'll have them all around the same level so you can go back to putting them all in parallel to finish a low voltage equalization.
2 differences: you do it with all the safety of a BMS, you're using 4 cells - instead of 8, 7, 6... so less voltage difference & slightly slower.
by the end of the process there could be 3 low ones, but they would have been there charging since the start - so should be close to full by the end.
