Thing is, Ishmael seems far more compitent then any Johnny seen (Yes I'm counting MGS4 Johnny too there.) so it seems really unlikely.

Also, Johnny was only recruitable in the Plus version/expansion of Portable Ops and really serves more as a Cameo like most others then an actual canonical character. His only canonical appearances have been in MGS3 and MGS4 and a brief mentioning in Peacewalker.
