Is there any evidence attesting to the fact that Rambam was even remotely familiar with the writings of any of the Ba'ale Tosafot?

The reason I ask is because Wikipedia makes the claim that the tosafist 'ELHANAN BEN ISAAC OF DAMPIERRE' was "often quoted by contemporary scholars, and is mentioned in 'Minḥat Yehudah', 'Shibbole ha-Leḳeṭ' and Rambam's 'Sefer Hafla'ah'." This suggests Rambam knew about some of the Tosafot. The footnote is a link to the JewishEncyclopedia entry but it doesn't direct you to any specific source in Sefer Hafla'ah and it all sounds suspect.

  • As far as I know, the Rambam never mentions an individual scholar in Mishneh Torah at all

  • There's a language of the Rambam in one of his correspondence where he refers critically to the baalei tosfos as something like "those cold sages from the north." I don't remember off-hand where I saw it, but I definitely saw it inside. When I first saw it, it was in the context of "the only place where the Rambam directly relates to the baalei tosfos." Try looking around in his teshuvos and igros.

  • I believe seeing that he corresponded with some during the controversy over his writings, but I doubt any would be referenced in his published works.

The reference is supposed to be not to the Rambam's Hafla'ah, but to the Teshuvot Maimoniyot on his Sefer Hafla'ah 4, which is in fact signed אלחנן ב"ר יצחק (with help from Gross' Gallia Judaica cited in the Jewish Encyclopedia's bibliography).
