Yes, Longinuses are said to be combinations of the abilities of different SGs but you cannot put Saji's SGs in that perspective since all of those abilities came from one source, Vritra.

Personally, what I'm getting from what you're saying is that Vritra, a Dragon King, is in the same league as Ddraig and Albion, the Two-Heavenly Dragons.
