'YT' I think you've started something here! It's about 30 years since I last built a radio and that was a 7 valve superhet covering MW and SW with a BFO and a Q multiplier built in. It was actually a combination of two published designs with some extras from the RSGB handbook.

Some time ago I came across a radio design using TV valves with push-pull ECL80's in the output stage. I think I might while away some cold winter evenings by getting something going. I suppose it's not the same as starting from scratch and designing your own and I have done that in the past. 40 years in the trade and I'm quite happy to build something that at least has a fair chance of working and then 'tweak' it to suit.

The idea of using some TV valves for a radio is sufficiently 'quirky' to be interesting.
