They were twins for about 10 minutes at the end of the third movie. Their twin relationship was definitely not "the big crux" of episode 4-6 and there is no way George Lucas thought this far in advance while making "A New Hope".
The way Lucas and crew had the whole “there is another” was vague enough that Leia could’ve just been another kid who happened to be force sensitive not Luke’s sister

It's unoriginal. The big crux of 4-6 was Luke/Leia twins and what that meant for their relationship to Aanakin.
Reusing twins again is kind of lazy writing.
