I do think that there would be significant interest in Young Picard, if he behaved like the one we learned about in Tapestry.
Unfortunately, the time-period where his stabbing takes place is not properly situated for any kind of a series. But yes, Young Picard was very interesting and dynamic. I'm convinced he would capture the imagination of a very broad audience. What a shame another reboot is required, just to explore that. There's canon, getting in the way, again ...
but what can you do? You know? What can you do.
