Given your schedule and the amount of time you have, I wouldn't bother with more than one distillery. While there are substantial differences in the end product, the manufacturing processes tend to be similar. There will be a great deal of overlap among the tours. Unless you're a real whisky aficionado, one will be enough. If you want to taste a variety of whiskies, a pub is the place to do it, not a series of distillery tours - plus, any two distilleries close enough to visit as a pair will produce whisky with the same regional characteristics.
(Think car factories. There are huge differences between driving a Toyota Corolla and driving a two-seater Porsche, but the differences in how they're built are much smaller.)
By the way - if you have enough time on Skye, the Talisker distillery has a fine tour.
