And Kohaku's ending really is too happy. I hope they give her a Normal End in the remake, or simply make the current one a Happy End and give her a different True End.

I don't think that is quite necessary. All you would need is to "spruce" it up by adding more internal monologue, which as we saw for Hisui's accounts, put things in perspective we would never see otherwise if we were not allowed to get a more leveled analytical viewpoint. We would see a normal meal in the Emiya household, but just with new participants, instead of people healing from pain.
