A lot of people think the Genelecs are ugly. I wouldn't call them beautiful, but I don't share the view that they're ugly. The black ones and white ones can look quite nice in the right setting.
They are also made of cast aluminum and incredibly solidly built, and the rounded edges serve the sound. Replacing that with wood veneer over MDF or whatnot would degrade the rigidity and likely the sonics.
I don't think you can do much about the shape, but I'm sure the technology exists to create a convincing-looking woodgrain surface on the Genelecs' aluminum covering. The questions are whether the production process is economically feasible, and whether there's much demand for a wood-veneer-look version of speakers with that shape and among the main customer base for this particular kind of speaker.
On the one hand I totally get the desire not to have to look at something one thinks is ugly - music is about aesthetics and enjoyment after all, and so being displeased by the things you have to look at while listening to it would be a bummer.
On the other hand, even though I appreciate fine art, sculpture, and design, I've never quite understood what people get out of their hi-fi gear looking like fine furniture. To me it's like wanting my computer to be clad in wood veneer. It just feels wrong somehow.
To each their own of course.
