It wouldn't exactly take much to surpass current Metroid ships, which are lucky to break a double digit total of fanworks ever.

I think the top ship by the numbers would be Samus with a human version of Dark Samus (so not even a real character from the series), just because a couple specific artists have had spates of publishing illustrations and comics of that. Samus and Gandrayda is the "top" ship involving an actual character, and that one is solidly in the single digit territory. And finally there's Samus and Melissa from Other M, which is actually a great ship, but trapped in a game everyone rightfully hates, having near-zero yuri fanworks.
