Your rank will not change.

Also, there is no such rank as Donor+

But there is.
It is seen as Donor+ in tab, but the rank itself is called superdonor. On PH it has no chat tag and has all the commands of donor with the ability to see asay. Good for undercover staff alts.
I belive on TTT it serves the same function, and has a rainbow chat tag.
But no, you wont turn into it.
