I'm in planning stages for a major kitchen remodel. Home built in 1984 with PEX plumbing, all electric, etc. We would like to demo the kitchen soffit (bulkhead) to make the ceiling level and install updated cabinetry. I cut a couple holes in the soffit to see what's in there. On one side there's some electrical wiring and PVC drainage pipes heading up to 2nd floor. On other side is some more PEX plumbing and an HVAC vent. I've attached some photos (but can add more if it helps). I would be comfortable removing the cabinets and demolishing the soffit drywall/framing. However, if I do that, would a professional plumber/electrician be able to relocate the plumbing/wiring to be behind the wall/in the ceiling? I don't want to demo everything only to find out that I need to put the soffit back on because of some permanent construction realities.
UPDATE (03/17/2020): Alternatively, instead of removing the entire soffit to the ceiling, would it be possible to raise the soffit ceiling by about 6"-7" and take it in about 5.5" to create a reduced soffit that could be covered with crown moulding? This would make room for 36" cabinets and still leave about 1" of clearance from the bottom of the DWV pipe to the top of soffit framing. There's still the electric and PEX issues, but those seems less apocalyptic. All pending measurement/concurrence from a licensed plumber.
