Who says one has to maintain centerline? With over 4,000+ hours in freight Beech 18s there are many ways to counter crosswinds. Upwind throttle is one way, landing crossways to the runway into the wind is another. I once landed a Beech 18 in a crosswind so fierce that I landed perpendicular (across) the runway. This was in a blinding blizzard in the Chicago area. Taking off from the same airport later, I had to use full throttle on the upwind motor & about 30% power on the downwind motor until I have enough controllable airflow over the rudders to go to mostly full power on both. You're flying a Twotter, not a 777. Use it like a truck & go home to fly another day.
