Nuclear Campaign help

I’m trying to make a nuclear theme campaign for a run but have not played with the expansions much. I have all of them and I have the gigalion, the killennium butcher, and the nukelope. My question/looking for recommendations on what would be the best way to incorporate the expansions to get the most out of the nukealope and dragon to make a nuclear theme campaign? Also who else would be a good thematic add (gorm, DBK, sunstalker?) not looking to min/max a campaign as much as I’m worn out on fighting white lions and the regular antelope and want to try something new with a newer group. Also do we know if they are looking to explore more nuclear type monsters?
