Kylo appeared in front of Luke because the dyad includes the ability of material exchange

So when Luke appeared in front of everyone on Crait, that was because of a dyad? The dyad as a concept didn’t exist when TLJ was written, yet water splashed on Kylo’s face in one of his conversations with Rey. I’m just not getting how the word “dyad,” with no further elaboration at all in TROS, explains anything that TLJ didn’t already. The only reason “Snoke did it” sounds implausible to you but “a dyad did it” doesn’t is because of your own assumptions about Snoke that TLJ as-written frankly doesn’t seem to support.

he orchestrated Kylo appearing vulnerable in order to lure Rey in

I’m not sure how that could in any way be credited to Snoke if, in your version, he had nothing to do with the mind-bridging. What exactly was he “orchestrating” and how?

Kylo seemed vulnerable to Rey because of the conversations they had, and they continue to have those conversations after Snoke dies. Are you implying that Kylo is acting out of character throughout the first half the movie because Snoke is mind controlling him?

This all just seems like a lot of hoops to jump through when the easiest and least-damaging options would be:

Let the audience assume that Palpatine doesn’t 1:1 control Snoke and/or the dyad isn’t purely the mental connection, which is what the theatrical versions of the movies do and what Hal plans to do.
or
Tweak the “voices” line in TROS to completely remove Palpatine 1:1 controlling Snoke as possible assumption.

I’d personally like to remove the word “dyad” from TROS entirely if it’s such a big problem for too many people. Just cut Kylo’s lines in the hangar, then in the soul-sucking scene just have Palpatine do it intentionally and not pause with surprise. But that might be too dramatic for Hal’s cut.
