By all means make it more BG-like by doing away with camp supplies and giving us the *occasional* random encounter. That is, random encounters that occur about as frequently as they did in BG, not the just once or twice per rest someone suggested in another thread. BG allowed the player to rest as often as they liked, with the risk of occasional interruptions. Requiring supplies and having interruptions seems to me not to add to the adventure, but take away from it. And to really devalue casters who need to prepare spells to be effective. When concentration is easily broken and too many spell casts are unsuccessful (excluding inappropriate casts against resistant/immune creatures), spells already feel like an unreliable resource, pushing us to rely on those few like MM that are actually likely to hit. In the earlier BGs Vancian casting was balanced through ready access to wands.
