It might work. But what if party members are scatered around the map? How about characters in combat trying to reach other areas in hopes of geting help from guards?
Without knowledge of internal engine design we are left with a guessing game.
For characters scattered around I would presume we have a few loaded areas, which may use different scripts and same scripts depending on that personal choice.
Characters in combat who's trying to reach other areas shouldn't get any problems with sane logic as for the enforced turn-based mode applied. You can literaly walk in it from one edge of the map to another, spreading turn-based around your character.
