I think it's mostly based on your art. Art from this angle should be straightforward to rig. Perspective changes are always pretty limited. If you have large perspective changes, then you often need different art. You can often use the same bones, sometimes more or different bones are needed.
I would start by making first doing the rigging that meets your needs for the perspective. See how far you can take that and if it doesn't cover the movement, poses, or other perspectives you need then add new art and possibly more bones to handle that.
