maybe, but ToA was all about a Yuan-ti city in a jungle, and I1 was all about a yuan-ti city in a jungle. ToA even used the title of I1 as a chapter title. To be sure, the city in ToA wasn't anything like the one in I1, but the similarities are still there...That wouldn't stop them: they published TftYP with Tomb of Horrors a few months before Tomb of Annhilation came out, and shortly after Storm King's Thunder with the Giant influence. I1 is still very much in the mix.
I'd say relocate it to the Hool Marshes (which do have a Yuan-Ti city somewhere, per what I can find), along with N1 in the north as an intro and I2 around the same area. All the reptiley goodness.
