I get the need for indoor rides, but Universal clearly wants the park consumption method to be park-to-park. In that case we're looking at Fallon, Minions, Mummy, Supecharged, Gringotts, MIB, Simpsons, Transformers, etc, in addition to all of the ones you've named. There's quite a bit of options for indoor attractions on property, but people have to spring for a park-to-park ticket.
