Does "WIMPS don't explain observed data" also exclude "matter in other M-Theory branes exerts a gravitational influence on matter in our own" as an explanation for dark matter?

The main argument I've seen against this is that matter interacting gravitationally across branes would cause a sort of n-body problem condition where everything in a particular sphere of influence would orbit continuously around the center of mass instead of settling into a lump, but maybe that explains why some planet-scale (or larger) objects have spinning cores?
