I don't think so! Gort knows of secret Dalek weakness - he will use his 'ray of vaporization' against the plungers of the Dalek's, creating a massive cloud of rubber vapor which will condense on the cold internals of the Daleks causing them to become permanently gummed up! Ha! Who needs plungers when you have a cool retractable visor??? Gort 4-ever!
But there's so many Daleks and only one Gort. They could surround him, even with their limited Dalek mobility. Gort couldn't possible vapourize and immobilize 'em all, before getting negatived. Granted, Gort is a pretty tuff mofo, so he could probably withstand a few negativings.
Princess Leia costume next year, perhaps? :)
