Can you build a pc keyboard with a laptop keyboard?
Theoretically.
Yes, it is unnecessary
It is, however, as my colleague 8agguetteYT said, unnecessary, only for the "feeling" it is not worth it. I have a friend who has that too but he says it was unnecessary. If you want to have a pc (gaming) keyboard it is worth owning a pc

It does go
Sure, if you're fit in electronics.
It doesn't really matter if it's unnecessary my mission is to save money
There are tutorials for this
No idea - never looked for it but. 😉
I'm not an electronics technician either - but the trickiest thing is the wiring.
I assume that laptop keyboards are not necessarily connected via USB.
In short: you would have to build a controller that would implement the keystrokes accordingly. Whether for this B. A Raspi Nano can serve… I don't know.
Should be an interesting project. Sorry that I can't really help.
