I have a comprehensive WeakAura compilation that might work for you:
https://wago.io/Ekb2iW5v-. Watch the two videos of Unholy to see what it would look like for you.
Currently is comprehensive for Unholy, about 90% complete for Blood (needs to track 4 more talents (Mark of Blood, Rune Tap, Blood Tap, and Blooddrinker) then it's complete), and has basic functionality for Frost (has Runes/RP, Frost Fever tracking, and Killing Machine/Rime procs). I will be updating the WeakAura at the above link as I complete more of this compilation, so feel free to check back in a few days and import it again.
Here are two videos as Unholy:
https://www.twitch.tv/tehrible/v/79711375 (shows tracking of the basics, plus Ebon Fever, Unholy Frenzy, Pestilent Pustules, Shadow Infusion, and Dark Arbiter)
Video is slightly outdated, Dark Arbiter now shows % damage increase in addition to time left
