It seems to me this filter is in a wrong place. 
RecoPixelVertexing/PixelVertexFinding is not the right place to produce jets based on rather minimal inputs related to actual pixel-related code.
I suggest this is moved to RecoJets/JetProducers (probably not a good place either) or to HLTrigger/JetMET (I'd start here, since you really want this for HLT at this point).


Please also check with the JetMET group
