Pick Pockets and Slight of hand were seperate? I don't remember Slight of Hand being in there at all.
Do keep in mind that, if you combine Move and Hide into one skill, you need to combine Listen and Spot. Otherwise you'll be opposing your sneak roll with 2 checks, which makes sneaking much less likley to succede.
If you Combine Spot and Listen, and Move and Hide, you've just given most Rogues and Rangers 2 additional Skill Points per level, as well as made it much easier for characters to be decently aware and stealthy with cross class ranks.
If you're cool with those changes, go for it. I'm still not convinced, however, that it's necessary.
