Good advice. Don't put both a 30 amp and a 50 amp appliance on one circuit. If you open up a space in the box for a 50 amp breaker you can run a proper 4 wire, 6 gauge conductor to the dishwasher.
This part of your plan is just craziness. Do not do this,
especially the part about sticking a 50 amp breaker in front of what may be a 30 amp circuit.
"There is one 240V circuit in the basement, directly below the kitchen. It is being used for a clothes dryer, using a 3-wire 10-30R receptacle. That dryer's manual says it can be used with either the current 3-wire receptacle or a 4-wire 14-30R receptacle.
What I am thinking about doing is: change the dryer cord to a 14-50P plug, change the dryer receptacle to a 4-wire 14-50R, run conduit from that receptacle up to the kitchen, install a second 14-50R receptacle there. I haven't checked if the current breaker on the circuit is 30 amp or 50 amp, if the former I'd install the latter. "
