It would be an interesting idea in the main game, but I think Larian is pretty committed to the hard CC at this point in development and would be quite reluctant at the massive rebalancing which would be needed for such a revamp.
For an independent modder working alone, the possibility of making a rebalance mod strikes me as low as well. I am not even sure it will be possible to make a mod to change the status effects for the main campaign.
