Now that I have googled your rig and see those low cabinets. They ARE low. I also HAAATTTEEEE bashing my head.
I am a hobbiest wood-worker. If it were me, I'd pull down the cabinets, since only screws hold them up and together, and modify the faceframes of those two cabinets immediately over the bed by trimming the bottom and tilting the faceframe bottom in 3 or 4 inches (or just 2 or 3, depending). you may get lucky and find the finish on the abutting cabinets is continuous on the newly exposed triangular areas.
If you are not capable of this, a cabinet maker surely could do it and would charge waaaayyyy less if you could do the de-install, install yourself.
The big problem would be if the cabinets are heavily glued with non-heat sensitive (hot-melt) glue. Then a new box would have to be made, but the original doors and faceframe could still be used.
Or just cut-off the back of the cabinets and re-hang.
