I doubt that very much. It's more likely they now count it as part of Unther given that Enlil, the Untherite Head God saved both of their biggest cities and many Dragonborn refugees, and they took in Untherites who'd left Gilgeam's forces. It's kind of taking on the flavour of a civil war between Untherite Gods.
Also note every Mulan God is gone from the list of Faerunian Gods, Sharess/Bast, Hoar/Assuran, Tiamat, Bahumut/Marduke all not on the list. We know Gilgeam and Enlil are around, but also not on the list. Could be seeing the rebirth of the Mulhorandi and Untherite Pantheons, or something stranger still, a unified Mulan Pantheon? Could more Mulan Gods get resurrected?
