Nice, but...
It won’t happen because the 4 man party is tied in with their Co-Op Multiplayer model so there’s about 4-5 other hard coded systems that make it necessity.
We are repeating these same arguments across a dozen different threads at this point, but just to summarize...
There would be NOTHING preventing co-op to stay as it is and STILL allowing to expand the party up to six slots.
Even keeping the cap to four players, IF Larian thinks that's a necessity. You could just make the multiplayer cap at four OR allow the two extra NPCs to assigned to the two most experienced/willing players.
Or, you know, raise the cap to six players altogether.
And a smart dynamic exp system (like the one used by past BG games or by, uh, D&D in general) would easily compensate for it: less characters in your party = more exp to each party members.
