The org chart is always just a suggestion.
RFK has demonstrated repeatedly that he has absolutely no principles whatsoever, and he'll sell out if a soft breeze passes by. If the agribusiness sector tells Trump that banning this chemical will cost them 10% of their profits, Trump will tell RFK to get in line, and he'll give a slight whimper as he does so.
The game of politics makes enemies one day become allies the next. If you want real progress on an agenda, being dogmatic generally isn't the best way to accomplish it (imo).
Trump Republicans very much dislike Liz Cheney for being completely against Trump during J6 investigations, and recent news implicates Liz Cheney in having tampered with lawyer relations for one the J6 testifiers [1,2]. Right-leaning commentary during the J6 investigations considered them sham investigations with the Republicans on the J6 committee often called RINOs (Republicans In Name Only), as those Republicans were anti-Trump.
This is the perspective that makes the Chenys supporting Democrats seem ridiculous. Other republicans supporting the Democrats generally have pro-war big government views which are largely incompatible with the new Trump Republican base.
I'll disagree that this was just an "endorsement of bizzare personality-cult fringe candidate" as these individuals all have some political pull and have been given substantial positions in the upcoming administrations.

Meanwhile The Trump-endorsing 'coalition' individuals in question are wildly unserious people, to the point that they're going to be laughed out of their senate confirmation hearings if they don't withdraw beforehand.

The GOP couldn't even form a coalition with itself, you saw a lot of people within the GOP who wouldn't endorse their candidate (the most stark example being the former VP). The democratic nominee coalition built to a fault. Many point to exactly this, and the failure to scorch the opposition to the degree warranted, as the reason for the loss.
RFK is your garden variety opportunist grifter, as are the entire confederacy of scammers and dunces (no offense, this is strictly a factual assessment) who are now on their way to positions of power based purely on their loyalty.
