I think the builds you're proposing are all decent, viable budget options. Good work!

I do take issue with all these builds together in the same hangar. You're proposing a hangar that runs 4 midrange-to-long range bots (Molot Griffin; Zeus Carnage; Trident/Pins Natasha; and Zeus/Gekko Natasha), and only 1 brawler (the DB Griffin). That is far too much range and far too little muscle with which to contest beacons. In fact, most champion league players run 4 brawler builds and 1 mid-to-long range bots.

I would recommend: (1) the DB Griffin; (2) choosing one of your proposed midrange builds; (3) a Punisher Griffin; (4) a Thunder/Taran or Thunder/Orkan Boa; and (5) Thunder/Punisher Leo. That would give your Hangar some serious muscle to bully enemy reds off beacons.
