Definitely possible. I'll look into it, and see about adding it into the near future. The location of the buttons could be overlayed or maybe put between the bars and the buff icons.

Any sort of "cure" indicators would be impossible as far as I can tell on the target window (unless you pinged the raid window every time you target changed). But I think just being able to cast by clicking buttons directly on your target should suffice.
