Mike;
I repaired an H-82 for a fellow, and I did what you did with the R-72, but I put the bypass caps right under where the block condenser can was located, reusing the original wires. A few years ago I got my own example of a CGE H-82, and have been debating whether to do the same, or restuff the can, but haven't done much with it since I still need to find , or make a pair of chassis mounting brackets, or slides for it, as well as find some tube shields that will fit the bases on the chassis. For whatever reason the S-42A used different diameter tube shields even though the basic chassis layout is very similar, the main difference is that the S-42A has push pull #47s rather then a single ended #47, with an AVC tube, electrically different, but still has eight tube sockets in the same places.
I will probably get into the S-5 Echophone since it's more complete, however someone had a go at restoring it, but obviously aborted the attempt, emptying the bypass condenser can, leaving the removed, and empty can, sitting on top of the chassis. Their bright idea was to try installing the bypass caps where the wires were connected, so there are a lot of disconnected things under the chassis, fortunately they did not break the antenna/R.F coils, but did manage to break the antenna terminal assembly, Why? This is an interesting set in it's own right, they have a pair of #45s in push-pull, but no audio interstage transformer, in all honesty I thought the previous fool may have removed it and lost it, until I checked the schematic. I think I will restuff the can, it was only the depth of a sardine can so it would not be difficult to fill the voids in it, the wires came out the ends through rubber grommets. I think it will be easier then your 140, but still not easy, but after working on an H-82 I know it will be about the same level of difficulty, but in a different way.
What some guys have done with those sorts of block condenser cans was basically to make a wood box to go inside the steel box, then they would mount terminal strips to the wood and mount the capacitors on those. I think these cans are spot welded together so they don't really need to be filled with something to stiffen them up.
