I have been thinking about this but after doing a few playthroughs I feel like there would be an outcry as this would actually cause more cons than pros if you really think about it. I will point out the most likely one or 2 that I see.
When sneaking around you see an overlay of red that indicates what will cause need for hide rolls/spotted. So typically you have to be very careful and sometimes move in a pinpoint precision path. With how the companions move as a group you would almost never be able to manage this properly without going turn by turn movement at which point you can make everyone hide on their turn to begin with.
The other point, and this is merely assuming that you were thinking a hide all would result in only the lead having to roll hide/sneak rolls when the reality is every character would need to roll. Now do you honestly expect Gale to be all that effective at sneaking? Or Lae'Zel in her metallic armor? They will be blowing your cover constantly causing you even more frustration.
