Best possible chance (which is unlikely just due to having to make 3 seperate trusts under the same name) would be making it into a trust at the end of its level cap questline that would basically mimic whatever setup it was currently in healer/dd/tank, but since it can already function in its current form along with trusts, i figure they'll leave it as is.
but she is at or stuck at the LVL 75 era
Trusts can level up to 99 after quests and after that work similarly to trusts in that they auto-adjust to ilvl based on the players gear ilvl
