I too have used the armature method for repairing Bakelite. Used that Plas-T-Pare from the US. It can fill really thin sections and years later is still there. I actually used it on the chipped dial covers (the parts over lapping the dials) of a McMichael 'roller tune' with no support at all, just bonded to the edge which cant be 3mm, they were flatted and sprayed up and are still there and its at least 10 years ago.
How is the cabinet finish up close? do you manage to get rid of all the orange peel? Sorry! you know I have the critical eye !
I find in these small chassis the modern caps look OK where as in a big 30's one they offend me.

Excellent invisible repair on the McMichael Gary!
Re 'orange peel', it isn't perfect, but it's acceptable. Not the best time of the year to be spraying of course. My little workshop is heated and double glazed, so I got the temperature up in there, and sprayed it as best I could. I gave it two coats of primer, three coats of gloss, and flatted each one with 'U-Pol pads as used for car re-finishing. As found, the cabinet was very faded and jaded, notwithstanding the damage, which was at the back and could have been camouflaged to a reasonable match had the cabinet not otherwise been beyond redemption. Besides which, I waned it red anyway!
The extent to which it the cabinet had faded is evidenced by the faded speaker cloth - originally bright green.
Re modern caps, yes, I agree - the older and rarer the set, the more that conservation comes into play. Although the caps aren't visible, we know they're there and they do look garish, it has to be admitted. I do re-stuff can electrolytics, as in this case, but I've only ever stuffed caps in pre-war sets in the case of the Ekco A77, which has stalled this last year.
You might recall the vintage repro caps that Colin Wood created some time ago. He rolled tubes from brown wrapping paper, printed a logo 'WESCO British Made', plugged the ends of the tubes with plugs he made from baked Plasticine and dipped the completed caps in paraffin wax. The end result looked very authentic. The ones illustrated are .05, .005 and .01
