And why in hell they would do that?! Your theory don't make any sense.
For religious reasons. For boredom, if they are immortal and grow tired of their bodies. For aesthetic reasons if they are a culture that has cheap biosculpture and a tendency to fads. It's a common Science Fiction trope in Iain Banks' The Culture series or in Alaister Reynolds' The Prefect. For instance, the very start of The Prefect is when the veteran cop and his rookie show up in a Glitterband Asteroid, and all the locals have biomoded themselves into aquatic merfolk for the sake of art.
Stellaris largely imitates Science Fiction tropes, and Alaister Reynold's popularity is great enough to ensure some spillover into its gaming, I think.
