I'm not really a fan of the writing of Harry Potter, it often falls into a trap of being a mystery adventure where the puzzles are then trivialised by magic which seems forgotten next time it would be applicable, and I like to try to race the characters to solutions which you can't really do in this format.

I'd love to write a TV show in the harry potter universe starring a squib (someone incapable of having magical powers who knows if the wizarding world) running a mundane repair shop for wizards in London near Diagon Alley. They'd basically be losing their minds at the regular cast of wizards being upsettingly inefficient and naive with their magical potential, while also running this repair shop for them that looks more like an antiques shop. It would definitely explore these questions as the protagonist pins down their wizard friends and makes them do multiple wand tests etc. The whole show would lovingly poke fun at the unanswered questions and plot holes of the Harry Potter universe and consistently paint the wizards as lovable but arrogant goofs who never had a proper education past 11 years old.

I don't think Harry Potter needs Binary Lasers, those are scary enough in battletech
