How about Athletics?
+2 to climb and swim. At level 10+, if you've put 10 ranks into one of those skills, you get +2 more(to a total of +4) in the skill you invested in.
Issue, climb and swim tend to have static DCs. By the time you're level 10, with 10 ranks, you likely have the numbers to make it through most situations. Assuming you're a strong sort with 14 strength, that's +12 by the time the +4 comes, and if it's a class skill, which there's a good chance of it being, make that +15 On the plus side, making it +19(with the +4 of the feat) means even in a hurricane you just can't fail to swim. You can also swim around the world without issue. You may get tired because you're up past your bed time, but the swimming part? You got this covered.
Of course, you'll be able to do that anyway at level 14 without the feat.
Onwards, to solutions!
Let's borrow from Unchained a bit. I do like the ideas put forward by Paizo in this book.
Leave the skill bonuses in, but also make it unlock the skill unlocks of one of those two skills, player's choice. To keep things fair, make taking this prevent you from getting any other unlock via feat, since you can normally only unlock one skill this way, unless you're a fancy pants rogue who gets it as a class feature. Go rogues!
Now there's a feat you can sink your teeth into! And it'll get better at 5th, 10th, 15th and 20th level!
But what if you let everyone have all the unlocks?
Then I'd make it increase your ranks by 5, for sake of unlocks, meaning you get them earlier. Let it do it for both skills.
How does this idea sound to you? I'd love to hear from you!
