It's not outside the realm of reasonable that there might be an aberrant class considering that true marks used to have several classes. Relax :D as long as they don't try to do like the bad old "artificer" Lantan/Ravinica versions it will be fine.
Morgrave Miscellany (unofficial add-on to WGtE, also written by Keith Baker) has Children of Khyber as a race option. The Aberrant Dragonmark is more of a feat chain (Lesser, Normal, Greater, Khyber) than a class with how it's listed, but it does give you limited spellcasting all the way up to 6th level.

It would take some effort but I think you could take a Fighter or Rogue and play them with some degree of success using primarily the spells/abilities gained from these feats.
