Try Quintessential Rogue, I think there was one in there.
However, if I were DMing, I'd let pretty much any feat like that go through, as long as there's some logical connection between the two skills (no feat for +2 to alchemy and intuit direction). I mean really, I've never even seen someone take one of those feats before.... at high levels, +2 to two skills is so miniscule, it's not really a big deal. Yay, you have +17 instead of +15, whatever.
