As long as the surface or structure is strong enough to handle to weight of the unit, then you'll always get some benefit from direct drive. However, if there is a lot of movement or flex, you will lose significant detail. In most cases it is possible to fit a direct drive wheel base to a foldable stand, but I have yet to test a wheel stand that is acceptable for direct drive performance (personal opinion).
While I'm sure it can be done, your wheel stand doesn't appear to be ideal for mounting a Podium Series wheel base - as far as I can see from the installation PDF, the wheel plate is only drilled for the angle mount that comes with the ClubSport wheel base; it's not drilled for the three-hole mounting pattern found on the CSL, ClubSport, and Podium bases. The reason for this could be because the wheel plate attaches to a square bar at the front, which restricts the use of bolts over the first inch or so.
As you can see from the drilling template on our site (linked by leonstone), the mounting points are very near the 'front' of the underside of the base, so there is a lot of (very heavy) overhang at the back. If you have to mount it 'behind' the square bar, you're pushing back the base even further. Perhaps it could be mounted towards the front of the plate by drilling through the square bar as well.
