Here's a link to a picture of a separator (not mine) which is similar to bennybmn's separator shown above. Sorry for the small picture, but you get the idea -- plywood donut for vacuum motor, plywood box to enclose filter and plywood lid on top of vacuum canister.

It would be interesting to know if this changed the airflow enough to make the whole setup either more or less effective.
I have thought about doing something like this, but I'm not sure if the space saving is worth any loss of efficiency.

From what I've read, the fact that the filter stays clean more than offsets any loss in airflow which results from adding a dust deputy to a shop vac. I haven't seen an airflow comparison of a shop vac/dust deputy combination vs. a shop vac with a drywall bag. Before you invest in a dust deputy, you could always try using a drywall bag in your shop vac.

I have a dust deputy, and I like it, I have also built a cart on wheels that allows me to roll the vac and DD setup around as a unit.
But since the dust can on the vacuum now seems large, and mostly useless, I am thinking it might be nice to eliminate it, like a couple of the pictures above.
What Im concerned about, is that I know that fluid dynamics is a complex field, and while it may be nice to make a small plexiglass enclosure to house the filter and eliminate the shop vac canister, it may significantly alter the suction that the vacuum is supplying to the Dust Deputy.
Currently like several of you, I have flex hose between the vacuum and the DD and it's a fairly tight 90 degree bend to facilitate having the vacuum and DD on the same platform. I know that if you can eliminate bends you improve flow. Maybe the guy with the Vac on its side did it that way to improve flow also.
I just got a new vac, maybe I will turn the old on its side, and see how it holds up.
