wouldn't the venting for the range remain the easiest from the current position?[avoiding more bends then necessary]. I'd put a reduced depth base cab to left of pantry-24 or 27 in width-needed for misc use when people come in from garage....then pantry,perhaps at the reduced depth[are 24 in deep pantry cabs really the best anyway?],then two 27 in cabs between pantry and fridge. Nice continuous counter in the kitchen....the challenge is choosing the cabs for each corner.Is the 49 in cab a special cab with the pull out peanut shaped things? Looks like the cab in corner by dishwasher can open out into dining area? that's handy...I would do a large single bowl sink and keep fridge and range about right where you have it.
