Sure Leyuna.. I don't see any problem with that.

I pretty much just use Pitbull, Infinibar, Aloft, Cow Tip, ElkBuffBars, SimpleMiniMap, Quartz, and Chatter to make the UI. I also have Cartographer, Quest Helper, Quest Guru, Fubar, ExperienceFu, PerformanceFu, ClockFu, and Skillet. (I think that's it).

Most of the smaller buttons I never use, I like to use them to monitor cool downs (I have hidden bar's with hotkeys for them). Oh I also use Cooldown count for a big yellow Cooldown timers on the buttons.
