Yes, it's a nice idea. And it has fun consequences, like black holes@LHC
The theoretical difficulty that follows next however is to explain why the extra dimensions are large enough to provide this dilution. In the worst case, getting this hierarchy of size of the extra dimension compared to other scales in nature is just as bad as getting gravity so weak in the first place. But that's just a technical concern, in the end we have to run the LHC and check for this kind of energy leakage into gravitons.
But anyhew, extra dimensions, and the usual concept of parallel universes, are kind of two different ideas.
