What I had thought about doing was hooking the UV output line up to a
small via aqua pump's air hose intake, drawing water through the UV
rather than pushing it through.

Yikes. I'm not sure that would be a good idea. You might have a lot of
trouble getting the syphon started.

If I were you, I'd buy a correctly sized powerhead. They're under $20 mail
order. And you'll need one anyway, if you're planning to move it around to
different tanks.
