Colleagues for a few more hours? Go for it.
It's all in the tone but I think you could pull it off. (The tone, not the VPL, though if handled right one could maybe lead to the other, dunno...)
If you hit the wrong tone though it'd be bad. It's basically one of those "does this make me look fat?"/ "yes" situations. (Not that VPL and fatness have anything to do with one another, but in terms of how it'd be taken.)
