I haven't, but I will say with lighting you have a lot of options. Obviously if it's a sealed unit, to change it out to a blue LED light you will have to swap the whole unit and splice a new one in. It's up to you if you want to measure it and look for a light that is the same size and shape as the hole. You could also look for any style you like if you are comfortable with cutting into the walls they are mounted to, to fit a new style of light. Most of the courtesy lights I'm seeing on my search are sealed units like that, but you can get them in different colors and styles.
Here's one I found that looks like it's a similar style, but there are tons of options you could go with. I don't think there's a direct plug and play option.
If you want to keep your factory housings, you could always dig into the sealed unit and solder in a LED chip like this.
