Aryaman does not look to have hotswappable pcb so you will need to unsolder the switches to replace them. You'll need to remove the back/bottom plating to access the underside of the pcb. It's easy if you've done it a few times, very nerve wracking the first time around. I don't believe gateron switches nor zealios are compatible either unless you shave off the two plastic mounts on the bottom of the switch.
Short answer: you can do it, but it'll be more difficult than just plug and play
