Got it. If it was the whole pyramid, my suggestion was to flip the middle girl back up to prep, and then have the side groups do something. That way all the groups had difficulty in them, not just one.
The prone full up you have is beautiful. I always like pushing that gray area! That's where you get the creative and different things that set your team apart. It can be challenging to make sure they're not seen as illegal though! If you want to stick with that idea, and make it more obvious, then my first thought is to make the backspot more visible. The way to do that is to turn it to the side or the front. Then you could do 1.5 or 1.25 up instead. It would have to be played with, but putting the backspot and flyer grip more to the front could make the connection seen better. Just some ideas. My other thought would be if the main or side base could be the contact instead of the back. You'll have to show us whatever you end up coming up with!
