I own a Ducky One TKL that I've modified pretty heavily. It's not impossible at all, it's actually pretty easy... But you do need to be able to desolder/solder. At any rate, soldering is a good skill to have in yer tool belt of tricks and messing around with keyboards is a decent way to learn. For education's sake, I would encourage you to watch some YouTube tutorials 'n pick up a pump n iron at the risk of ruining your board, but I am a maniac. Most will advise you to just sell that one and get another with lighter switches... They're probably right. But... Your brain... It must growwww!!
Edit- Why did only half my post submit... Hmm...
