On first glance, they look like Jean and Emma to me.
I think what's going on here is that the psychic mutants are astral projecting to form a collective construct of their own to try and repel the Uni-Mind.
EDIT: Though on second thought it looks like they could be Hope and Destiny as well.
Wait, do people really think that Percy came up with robot Moira idea on his own and then the rest of the X-group were forced to expand on that idea?
It always seemed clear to me that Moira becoming a evil robot was something that the X-group collectively decided was the direction they wanted the character to go in - look at how quickly Duggan and Gillen integrated the Moira XI idea into their stories, FCBD 2022 X-Men (with its identity-stealing Moira) had to have been written late last year in order to meet its publication date.
They got Hickman to introduce the evil Moira idea in Inferno on his way out (in order to lend it an air of legitimacy) and then Percy executed it the rest of the way in XLoW/XDoW (which was the first X-books event after Inferno).
