I would suggest crediting the AS leg to AA, and the VX leg to AS (which I have to assume is possible). Of course, if you open a VX account and credit there, it'll all end up in the same place at some point.
Currently, VX points can be converted to AS miles at a 1.3 ratio (one VX point = 1.3 AS miles). I assume that conversion rate will hold true until the end of this year when VX Elevate disappears and all VX points are "auto" converted.
