Is making all the lights on my pedals purple a realistic project?

I really want all the indicator lights on all of my pedals to be purple. I just . . . really like purple.

Would it be reasonably possible to do, either by myself or by sending them to someone?

Render of my board attached instead of a real picture so you can see which pedals I have (maybe some are easier to do this on than others etc.) because some of them are still on their way to me.
