Yes, but only to modify stats/Pokemon to legal/ intended limits

If it's legal, who cares how you got it?
This. As long as it's something normally obtainable in the game without hacking, go ahead and hack it.
Also, hacking something outside the legal limits to use only in single player is fine too. I once did a Pikachu solo run in Yellow, but hacked it (after I got the 4th badge) so the Pikachu had Raichu's stats, but it would still learn Pikachu's level-up moves and still follow me around like Pikachu does in Yellow.
