Open up that entire section of wall from ceiling to floor in that stud bay, buy a new 200 amp main 40/80 panel with a main breaker (get a "pack" that comes with a bunch of breakers all for a special price) and tag everything and change it out. At the same time, replace the service wires from the meter and replace the meter socket with a new one with a disconnect and get the power company to upgrade to a 200 amp service.
Make new wall panels to fill the wall above and below the new breaker panel (MDF or similar) and screw them in. In the future changes are easily made by unscrewing the panels and accessing the top and bottom of the new panel.

Yep this is what I am doing ^^^ , . I always put some spare cables up and down and terminate in J-boxes for future use also. .. Since the service panel is in sort of a higher traffic hall, I will be putting drywall back and slick finishing it, in lieu of access panels.
The old gyspum board is tough stuff to cut out on the 1959" hard as a rock studs" but my sawzall made short work of it. .... I started on it early this morning, what a mess I made. I think the missus is going to take the Stihl chainsaw back she gave me for my birthday Friday, it is that bad, even with plastic walls up...
Since I have all gas heat/water heater, I'll just be putting in a 150 amp - 30 cir Sq. D service with the through the roof mast overhead. The POCO will be telling me what I can put in for sure ( 150 vs. 200 amp) , as they will not likely change out the transformer that 3 houses are now sharing with me. ....
Sorry for the sidewise pics but the hall is not wide enough to get wider angled pics. The pic of the 10/3 NM cable on the concrete patio is what I removed today from the crawlspace that was feeding the 3 ton A/C condensing unit. It appears the AC was on the end of the house originally, then they moved in to the back center of the house by the patio. Duh, how does one talk over a condensing unit running by the patio ?... The Type S- two fuse box was operating the A/C....
The homeowner ( I hope a HVAC tech did not do this wiring ) just "western union" type spliced the tap (the spider legged thing) in to the 10/3 NM and taped it for his feed to the condensing unit. Note all the other tape jobs also.
I am going to be a busy fellow, getting this old house wiring mess fixed. But I am not skeered though ( scared), but I am gonna be tired and it is going to take me a while now that I am long in tooth and not what I used to be. .
