Easy OmniTrack

I've been doing some thinking on this idea, and Here's what my brain has come up with:

Without any idlers along the main bulk of the Omnitrack, the weight and grounded traction area (pardon my incorrect terminology, I'm very tired) is only the two drive sprockets. In any track system, the presence of many idlers is what gives it the advantage over a standard wheeled system. However, the track would give it the ability to climb over stairs, assuming the links could hold up to that force.

So this design wouldn't really aid in the pushing ability, it would more of make an omni system that can climb stairs, which hasn't really been seen before in FIRST, unless I'm mistaken.
