Yes, this is possible..
You can achieve it with the UpdateList operation of the Lists service. ONe of teh input options to this method is updateFields - that's the one where you would use to re-define the values in the choice Column.
Note that the update can only be done by someone that has full control to the List. Also, For Choice columns, I think you have to actual update with with all the values you want it to have; you can't just say "add one more" to the existing set of values.
