My personal taste is, I like to often replace my hi hats with tambourines. It completely changes the feel of a track, most of the time for the better. I like to put a lot of reverb on bells and use them as counter melodies in the background. I like to put my crashes on the 1 with kick to bring some energy. If I use a ride its usually a 4x4 to get a constant head nod, (I typically do hip hop beats). And if you're looking to specifically spice up your percussion you don't to have to go directly to percussive instruments. You would be surprised what a simple bleep, blip, zap, or ting can do for a drum pattern. Take a bongo hit pitch it up 8 semitones or so and see what you get, or maybe a tom drum hit, or triangle. Throw some effects on it, change the tones. Im sure you'll come up with something you like.
