If you haven’t tried them yet, Abyssal Deadspace fits pretty closely to what you’re after. Each site is ~20 minutes with varying difficulty, and you can do it either as a single Cruiser/HAC or 3 Frigates/Destroyers co-op.

Pochven also has some more challenging PvE(vP) content, as well as some escalations in low/null sec (though those are a bit less reliable)

Let us know what you end up with!
