They won't do it, but it would be baller to set it up like a debate, and have the moderator prompt the empty Trump lecturn and have the camera hold on it for 5-10 seconds each time. It would effectively just be a Kamala campaign interview, but with a bit of shade casting between each question.
Everyone forgets but trump dropped out of the town hall debate with Biden in 2020. Biden actually showed up and just did the townhall by himself. He came off pretty well but godamn did he look like Jeff Dunham's puppet Walter because they had him squinting up at a mezzanine of questioners with all the lights in his eyes.
