I hope not. Re-watch "Galaxy's Child". I hadn't seen it since I was a kid. Totally different experience now. There's so much I didn't get, that I wasn't thinking about back then, that it was like watching a whole other episode.
That "romance" was strictly one-sided. Brahams tried to be completely professional the entire time and then this guy comes on to her because he likes her and automatically assumes she'll like him too. Without even trying to actually get to know where or find out more about her first. Like... her being married. For one. For another, setting up that dinner date which, like Brahams said, wasn't appropriate.
"I like her! So she'll be my girlfriend!" That's junior high, early high school type thinking. Which is why I didn't pick up on what was wrong with it back then. But watching it now... that makes Geordi look really bad. Setting aside whether or not Brahams was married, not even once does he think about what she might think. A relationship is supposed to be two-sided. Geordi only viewed it one way. Everyone else in the episode realizes this except Geordi, and that's what redeems the episode, but he himself doesn't come off looking very good. It's like he was a 13-year-old trapped in man's body.
So, to have Geordi and Leah be a couple in Picard would be a huge mistake. It's rewarding adolescent thinking in what's supposed to be a show that's geared towards adults. PIC, more than any other Star Trek series, is aiming to be "mature" and "adult". So this would undercut that completely.
