Yeah, unfortunately, that's not going to happen. They didn't implement the same thing with RSE and ORAS, after all. I think, at the most, they'll give you a certificate like this if a Pokémon that originated in FRLG is transferred to the new remakes.
(As a twist for a Yellow remake, maybe they could use Yellow sprites for Gen 1 Pokémon and FRLG sprites for Gen 2 and 3 Pokémon on the certificate, since obviously, nothing from the original Yellow would be transferable to the new remake.)
