It wouldn’t make sense.
First off Big Bang Theory only ended in 2019, ~5 years ago. Second, Young Sheldon just ended earlier this year in 2024. Third, as a franchise a spinoff of Young Sheldon starts later this month. So canonically the universe still exists and is being written.
Fourth, if you’re going to do a reboot it wouldn’t actually include Jim Parsons, the closest option would be a “How I Met Your Father” style spin off (same universe as “How I Met Your Mother”), which would probably just be a cameo.
But also, most of the Big Bang Theory actors are busy at the moment, give them a few years and I’m sure they’ll be up for something small.
It’s a show about Sheldon’s older brother and his first (in universe know to be failed) marriage.
I didn’t watch Young Sheldon, so I’m not sure if his brother and his wife can maintain a show. On the one hand it sounds pretty generic, so really if the studio was going to greenlight a generic sitcom anyway, why not use characters some of your audience already knows. Maybe we get something like Frasier.
On the other hand, it sounds generic. Maybe we get something like Joey.
