Yes you could do it that way or use the 3 section can as it is only instead of hooking up the one section that has the reverse polarity use it for #52. The reversed cap you can use a smaller 10 or 20uf @ 50v separate from the can. Just so you know this is sort of unusual as most sets don't have these multi section cans with a section or two wired backwards. Most older set will have just a few single caps which may have a paper insulator to isolate the metal par t of the can from the chassis.
