Max Keyboard Das Keyboard

I have two pretty standard 87 key TKL keyboards (one WASD, one Das Keyboard if it matters). But I use them on Macs almost exclusively. I feel indifferent between ALT and OPT. But I'd really love to have 2 CMDs. Can I add them to the TLK kit? Or at the very least, can I have 2 SUPERs? Thanks.

How will the Planck benefit me as a journalist and as a professor of English? Other than I can carry it everywhere. I think each student and faculty/staff member should have their own portable keyboard as a safety precaution since COVID-19. Much easier to disconnect and reconnect a 3.0 port on the front of the school's machine opposed to cleaning the keyboards between classes. IT can easily replace ports or computers. The Drop Alt is a log. So I am getting a Planck to lead by example. I am sure that many will have questions about the Planck. Can I easier navigate through a document? Anyone feel a Preonic would be better for my fields?

Can I change the RGB on this keyboard to be one static color through software? I like the keyboard, but I'd prefer to just have a white underglow, or maybe a softer blue. Something that isn't so distracting.
