You can get over any reaction to uneven weighting pretty easily, esp. if the difference is 1-2 lbs. Use at least a couple small weights so the unbalance is just 1 lb. You should be able to get used to this difference, many people carry canister lights, reels, stage tanks etc. without changing their weight configuration.
If it really bothers you, then dive with that extra 1lb of weight.
