A joint show sounds good too 
How about a show about the Nerves project? Perhaps following the same theme as shows about specific things rather than specific people (so can be more than one guest on the show). I guess you’d probably need to experiment with the format.
I’d also be interested in hearing Evan Czaplicki’s thoughts on the work they are doing for Elm/Phoenix integration and even his thoughts on FP and Elm in general. If you look at our ‘What other languages interest you’ thread, Elm pops up frequently.
