I think they've already been hinting very heavily at this.
Luq Begg, G'raha and Urianger have told us that for the transfer to happen, they need to find a way to infuse the crystal vessel with the Blood of Allag. So far they've been unsuccessful in their attempts.
But we already have crystal infused with the Blood of Allag - it's part of G'raha's body. This is something he chose to do to extend his life past its normal limits until the WoL could be brought to the First to end the threat there.
It's also starting to consume him rapidly as we see it spreading throughout his body in the trailer. His left arm is now crystal as well. His chest has crystal spreading He will die once too much much of his body has converted to crystal.
With his death, his body could potentially become that crystal vessel needed to house the souls of the Scions as the WoL returns them to the Source. The WoL could never consider a living G'raha his possession but G'raha's body being returned so it could be buried on the world he sacrificed a normal life to save? No way is the WoL going to allow that body to get lost on the way. And it probably helps that G'raha had made his original trip to the First possessed of his body, unlike the Scions.
Even if not his whole body, a portion of it like his arm would likely serve.
