That's not a particularly likely scenario imo. Getting back in shape and form for a return will be a lot of work for her, going through all that just for a few tournaments would be a waste of effort.I bet that retirement is closer than we think, sadly. I think she'll come back after reinstatement play a few tourneys and then call it.
I think she'll look at the ban and either retire (likely if its 2+ years) or make a decision to wait it out and come back. If she does so, I think she'll at least play one full season, possibly more.
