Having played with party limits removed and with a regular limits I do think the 4 player limit is restrictive on content and 6 is more reasonable. I myself prefer 8-10 character parties but bringing every character seems over the top Ive done it with party limit be gone mod and honestly even on tactician you can end every encounter with 1 round of combat. While playing a normal game 4 is ok and it can be done on tactician i think a party of 6 wouldnt hurt the game that much a party of 8-10 is overkill on normal 8-10 would make tactician it basically makes the game feel like story more by adding 2 characters and thats fine. Higher difficulties with more items would be a great addition to the game. Also a mild adjustment to UI placement of Portraits for this.
