Well this is major overkill for LVL 4s and nullsec anoms. That is of course depending on the rats you face. Guristas and jamming can be a real pain, but in general the amount of dps you have is a huge 'tank' in of itself. They jam a ship, you primary the jammer. Sanshas could be a real pain with their insanely powerful tracking disruption. Serpentis, well their damps can be a bit much also. In the end, you're murdering the most annoying rats first and then you're pretty set.
WHs though, that's a whole different ball game. They do omni-damage, neut from long range, web, scram, the works. They love to murder drones if you're using them a lot. They have RR themselves. They are pretty tough. High class wormholes, c4 and up are where multiple ships really come into play. Most people eventually drop carriers and dreads in c5s and c6s. This is done for the tanking and dps, as well as when you drop capitals in c5s and c6s you get extra battleship spawns. That's where the major isk in WHs comes from. But you'll need to loot and salvage it all. Then haul it out and sell to NPCs/market. Generally field trips into WHs aren't that good of an idea without a dedicated cloaky probing ship to get you out if your connection dies. If you really want to learn about WHs, start in c1s or c2s with some battlecruisers like the harbinger or prophecy, maybe even some t1 logi ships and see how you like things. If you really like it, you'll probably end up living in a WH to make it worthwhile. There's another set of headaches with the POS, fuel blocks, defences, constant probing for new WHs opening, getting eyes on any new holes... WHs are definitely team efforts if you haven't gotten the gist of it yet
So if you're looking to take your insane 7 man team and farm isk like no tomorrow, I'd recommend nullsec. Renter corps are an option unless you want to play in the big leagues i.e. get into null fleet warfare.
A word of warning though, at some point, which I'm not sure based on your setup, you'll hit a terrible point of returns. You'll be making very good isk, but the isk per account won't be great. I know this as I'm running 5 toons in null at the moment. I crush anoms but there is lost time in flying to the next one, setting up cap/rep chains, wasted dps on overkill for some rats (in my case I assign sentries to a target caller, this could be improved I suppose by having each toon lock targets and engage multiple targets simultaneously). The other issue is the salvage. Guristas salvage sucks, but other rats can yield very nice salvage. At times the salvage can be more than the bounties of the anom you just ran. Trying to multibox my dps team while salvaging for me is a major pain, so that can hurt isk per hour. You could split your rape train team into multiple groups, but then you're really starting to work to keep everything under control and dps constantly applied where it should be. Once the work word comes into it, I just throw up my hands and say piss on it. I'm making good isk to buy shiny things to get blown up. But I'd rather not have to 'work' while playing a game.
Well, take everything I said with a grain of salt. Try things out for yourself and have fun. If all else fails, you can always try and sell your toons on the character bazaar
