Could be. All the effects look cheesy enough to warrant that. Pond5 and Videohive have tons of AE templates, but there's just as many otehr sites, so unlesss someone already has used the same preset, I doubt you will get an exact link. Also check Red Giant People and similar free resource sites. There may be some preset that you can modify easily. And of course this may be entirely based on some tutorial, but likewise, since nobody can know them all, you will have to do some digging.
Having seen some of the sophisticated work you have done in AE, I think a good tutorial on using Trapcode Particular, AE Stroke (or Trapcode 3D Stroke) and Flares could easily give you the knowledge to recreate this yourself. Check here for similar kinds of tutorials.
Particular and blend modes. Maybe a little Knoll Light Factory... OTT there's not much to it.
