Essentialy what Star Trek did with the original series and Next Generation, but done while the show still runs or in between season, rather than happening after it ended.
Perhaps with leaving some characters like Wolverine out or reduced to guest appearances, so they can reserve a high profile actor for him, which would have the benefit of making his appearance in the show and movies alike more striking, rather than being just the attention hog.
Of course this is just an oddball idea and doesn't match the pattern Marvel studios is so very keen to follow because it worked for a good chunk of he MCU's golden age, but the X-men arguably have a problem that the 2 hour movies can never deliver on what the majority of the IP's fans know of them from pop culture and previous cartoons and the MCU version has an uphill battle to not also fall into it and just feel like the "Wolverine show, guest staring the X-men", all over again.
And yet the Guardians of the Galaxy worked despite also being a full team assembled from scratch (rather than previous movies) and filled with characters who were complete unkowns to the casual audience (all Avengers characters had appeared in cartoons before).
However it should also be considered that things were stacked a lot more in favor of the Guardians (better character designs, better personalities for the characters, better supporting characters, better setting, better villains, better development, a stronger director's vision, stronger ties to the "event story" the MCU was heading towards, appearing during the pre-Endgame "heyday" of the MCU, etc.).
And it could indeed be considered possible that The Eternals was a test run of sort, since the idea of an ancient group of earthly super beings could appear with the implication of always having been around, is pretty close to one of the assumption about how mutants could have existed in the MCU.
Likewise delivery is very important, whereas the post Endgame MCU has been rather lacking in that quality.
And the X-men actualy have a rather major disadvantage in that they are allready well known to most of the casual audience, so rather than having a complete blank slate potential like the Guardians, the X-men actualy need to compete with... well themself and their various previous incarnations.
