I don't see it happening, for a few reasons.
1) It would make hacking accounts worth it. Yes they recently did gifting, but it was for a limited duration.
2) It's such an edge case, very few people actually play enough to have everything unlocked, and that percentage drops as time goes on.
3) There are a few abuse cases I can think of, one being that creating a new account to farm IP would give you a free minor IP boost, as well as the RP to buy another boost (or two, I forget how much they cost).
Edit: Oh, and this doesn't really belong in this forum, the only reason one would put it here is because they're looking for support from people hoping they would be getting said IP.
