I would think that anyone close to Tony would try -- Rhodey, Pepper, Carol, Reed, and Maria Hill, Peter, and Hank Pym depending on where you're going with this. In terms of who would actually be savvy enough to do it, I would guess Reed, Peter, or Pym, though Pym is apparently on an outs with Tony now. Rhodey might be able to if his tech savvy has gone up now that he's a cyborg, but he didn't seem to be too good at the techs way back when. Oh yes, and Maya, if they'll let her out of the asylum or wherever they tucked her away to.
