You essentially want to replicate the visual appearance of actionbuttons without making them secure frames.
If they are not secure frames then anchoring them to your personal resource display in-combat or not is not an issue.
So shift your focus to that would be the suggestion.
The easiest way would probably be to create a "actionbutton lookalike" display with weakauras and anchor it to that frame.
