Jet Creations is a fabricator of inflatables. It looks like they have lots of off-the-shelf designs. For example:

(I don't think the sexy model is part of the product line, though.)
And perhaps most amazing (at least to me) are the inflatable costumes.

You can get off the shelf an inflatable "soul brother" with comb in his afro.
OK, I am joking around, but really I see a lot of artistic possibilities here where an artist either hires a firm like Jet Creations to fabricate an inflatable piece of art, or simply figures out how to do it herself. We're a city that loves its giant inflatable gorillas. I think we, as a city, might enjoy some giant inflatable art--in whatever form it might take.
