It's amazing how a 2hu ended up being created as a throwback to that dialog. Alice and Marisa are that good of a duo!

I didn't know that, I always thought the "special character" thing was more general, but it makes sense in this way too. There is a certain fittingness to it being a combination of the two.

I forgot to say this in the original post, so I'll say it now. I think the two main differences between IN and SA Marisa are these:
IN Marisa interacts more with the bosses, while SA Marisa talks more to Alice. I'm split on which one I like more, they both work in their respective environments.
IN Marisa sticks pretty closely to her gimmick, she is carefree, adventurous, boyish, likes to talk smack and lives in the moment. SA Marisa responds way more to her environment and is more fleshed out and flexible. I like the SA style more here, but it makes sense that an earlier game would give her a less complex personality to establish who she is, while a later game would expand her character.
In conclusion, I think I still prefer the SA dialog, but I would have started liking Marisa way earlier if I paid more attention to the IN dialog.
