Um... I think that if it were written completely by JKR, yes

If it's completely unlike the one-layered lasagne that is Cursed Child, I'd HAPPILY give it a read.

I honestly think the expectations would be far too high, the story would be plastered with all the little add ons from JKR and I'm not sure if that would be good. I'd like to keep the magical world in their original form in my heart, rather than seeing it get dragged through the dirt for a moneysqueeze and have the picture ruined.

That's true tbh
