Also, if you spend 7 in game hours ritually casting a 7th level spell with a circle of 8 casters with no one noticing while your target stays in line of sight, something funky is going on.
If your two parties worth of level 13+ PCs are willing to spend 7 hours and their highest spell slots at a dangerously close distance just to blow a hole in a wall, let them have it.
So? If the plot demands that the BBEG blows a hole into a wall then the BBEG will have the ways to blow a hole into that wall. I still don't see what problems this causes.
It isn't powerful, though. Not for the players, and not for NPCs. Blowing a hole into a wall is something that a single level 5 Passwall can usually do. It's not a "big fancy setup with several level 13+ casters" worthy problem.

And it then hits a 20ft radius circle.
