There's a story reason for the 4 man party limit? Please elaborate. Apart from companions going "it seems there's quite a few of you already" when you try to recruit them with a party of 4 already, I haven't encountered anything to suggest it.
I guess not, only 7 years of encounter design and many triggers and PC's placements all over the whole word. Something small and easy to change on the fly. That said, I'd be favorable to this option if it was proposed. Every option is a good option.
