I think this mixes up qualia and the electromagnetic spectrum a little too much.

From the angle of the basic science, sure, it is possible to see more of the electromagnetic spectrum; some organisms do see a bit more. Seeing all the electromagnetic spectrum though... well that wouldn't really work. You realise that visible light is the part of the spectrum with a wavelength of only 400 to 700nm? There are many other types of wavelengths, such as radio waves, which can be in the range of kilometers.

Regarding qualia though, which is what I think this thread is really about...

Well it's interesting. I think potentially you can be introduced to new qualia, yes. Our brain makes qualia out of distinct experiences. If somebody was locked in a blue room for most of their life and then let out, I don't think they'd see the world in blue.
