That is why I got a vintage folding camera -- Kodak Duo. I bought one of those (actually, two... but only one resulted) specifically because it was 645 in portrait-orientation. Besides, it has a mediocre triplet lens that seems quite nice for portraits as long as there is no intent to get close-up.
