Yes, if there is an Eldian somewhere in Mikasa's ancestry, she would certainly be able to turn into a titan according to this theory.

My theory is that Mikasa's Asian/Ackerman ancestors are not affected by the Coordinate simply because they are not of Eldian descent, and therefore do not possess the "Titan genes" which would render them susceptible to the Coordinate's power. In contrast to our previous assumption that they are somehow "special" races.
