Thank you to Welborn for coming up with a coverless Batman 9.
Here's a consolidated list of full covers only. Again, I haven't listed the coverless as I imagine it'd really be tougher to find a cover to a coverless than vice versa. These are also issue that may only need a centerfold where a coverless would be useful.
Looks like catrick 339 either has a cover for Superman 5 or a coverless Superman 5 not sure what he has but a coverless superman 5 would be needed here twice over.
