You can cut-in openings and sections where wiring is needed instead of destroying all the plaster. The repair cost will be cut significantly and the electricians can still do what needs to be done.
You will want a new grounded service panel upgraded to 200A .... dedicated circuits to kitchen and laundry ... fully grounded and circuit protected with GFCI ... receptacles for modern electronics (may as well bury a pair of HDMI cables for your big screen TV) ... ceiling fan boxes ... recessed lighting in kitchen and bathrooms ... 20A and 220A receptacles/circuits in garage for shop tools ...
THAT would be a fun project.
