In the context of 'what might have been', I've been using some software to produce a representation of what the Solo kids from the original EU would have realistically looked like (as adults / young adults).
Jacen, Jaina and Anakin.
I'm of course no big pro at this, but it's fun to play around with the possibilities. They look kind of expressionless because it requires decent pitures of Ford and Fisher as a 'starting point'. Finding good quality pictures of those two at a young age, and also facing the camera directly, isn't all that easy. (Also, pictures where one has a grin and the other doesn't, for instance, are hard to merge. So relatively neutral expressions are best.)
This is just a singe image, but it gives a bit of an idea of what these characters would look like, going by how they're descibed in the books, and then working off their parents' looks.
One day, I hope, we'll see the technology mature that will bring these characters to the screen. As I've argued before, I think advances in tech will ultimately allow for an 'actor-less' simulacrum of live-action, using neural nets and stuff like Unreal Engine 5, within 1-2 decades. By 2040 or so, it should be possible for a bunch of fans to literally just put the whole EU on screen, from Tales of the Jedi to Young Jedi Knights. And everything in between.
