With all due respect, what on earth are you talking about? The filtering idea is much more complicated than you'd think, and almost certainly won't work. Laser safety glasses are typically sold for specific wavelength sets. However, the block isn't all that precise - typically you just filter out the entire neighbourhood. Look at the Optical Density vs. Wavelength graphs on this page: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=76... . Now imagine trying to combine a whole bunch of those to cover all commonly available laser diode wavelength groups. Your laser-proof glass would be nearly opaque!

Even if we're extremely optimistic and have invented some new sort of very precise optical filter, you're still looking at dramatic reductions in visible light transmission which I would have to believe would be a huge safety implications.

Which is very cool, but still very experimental and appears to only block a single frequency range (not what OP was proposing). I've also yet to see any published specs at all for the stuff (i.e. what's the actual optical density at those wavelengths?), so I'm a little skeptical still.
True, but on the other hand this seems something useful to keep researching.
Build a windowless cockpit and feed the displays using an array of cameras with different filters on them composited back to full color.
