The Vf-1 J supposedly comes with three sets of hands... holding gun, open hands, and fists.... maybe you could have one holding his gunpod, and the other clenching fists.
Sorry - I meant for Roy's DYRL VF-1S -- since with the TV-style FPs (and addition of TV style hands) it could then be used as a TV Hikaru's VF-1S. I assumed that's what you were intending to do from what you said in your earlier post that I first replied to. Or are you suggesting that we would be able to replace the existing hands on Roy's DYRL VF-1S with some of the extras that come with Hikaru's VF-1J?
