Is it possible to have another preset that makes ghosts behave as close as possible to the old ones?
Do you mean removing the "delivery" tint?
If you want to do that, just set the "delivery" tints to be the same as the normal ones for each type. That will mean that the ghosts never change colour.
This mod can only change the tint colour of ghosts, and nothing else about the way ghosts are rendered is affected. If I have misunderstood let me know, sorry it took me so long to reply.
