Yeah, a Tupperdor on ROIDS!
I could imagine using that for singles/5-ers, now that you mention it... I have 2 100ct humidors (Which hold, actually, around 75 each) that I use for singles and 5 packs in my active rotation... Boxes go in the Coolidor (By the way, I built, verbatim, the "budget Igloodor" on your igloodor.com. Works perfect, thanks for that!)
It might work out better to just put singles/5ers in a travel humi... I open it at least once a week anyways, and then it would be easier to move around... And if it ever fell off the stand I wouldn't worry about it... Can't say that for a wooden one.
