Of course you can. You can also put Fender strings on a Gibson. Nothing bad will happen. Just make any necessary truss rod adjustments if you are putting different gauge strings on a guitar.
You Buy Your Preffered Strings. Then You take your old ones off. take the new strings and depending on whether you have a strung through back guitar or a removable bridge you put the strings either...
you can but it may require routing the guitar body like how kirk hammet has ESP guitars that are strat style but under the pick guard he probably has whats called swimming pool routing. seriously...
