You know your stuff, so this appears to be a challenge.
Worst likely case.
(Assuming no other sizeable segments,) Blaine Bettinger's collected figures for aDNA suggest that this could be anywhere between 2C and 6C. http://thegeneticgenealogist.com/
He also has X ancestor charts, but you would already know that on each side you are looking at the mother's side of each.
You can apply his % average inheritance figures for X, but they apply only very, very roughly, as X inheritance variability is high.
Why don't you try the GEDmatch Tier 1 prediction tool for X?
