Depending on how much control you have over the bundles providing the types you could also look at providing your own extender capabiltiy/requirement model which would further restrict your search space, and potentially allow further optimisations. You should take a look at the OSGi CDI specification from the enterprise R7 release (currently in draft) which does something very much like this.
