OP: Your situation is pretty much what I face myself - 2 teles, but one seems best for "normal" playing, and one dedicated for slide.
Since I love playing on baseball necks, my '51 Nocaster tribute build sticks with 10s and a normal setup.
The other telecaster is a Blade by Levinson Delta T-2, with a skinny neck that is perfect for slide setup in standard tuning. I've got it strung up with 11s, and action ever so slightly higher than normal, with some relief added as well. Between the higher string tension and the slightly higher action, it's great for slide playing.
