You cannot; just as Palkia is exclusive to Pearl, Dialga is exclusive to Diamond. The only game in which you can catch both is Platinum.
Yes if you want it on pearl
They are both equivalent, with minor changes, such as Palikia in Pearl and Dialga in Diamond. The only thing that changes is the Pokemon that appear and what time.
dragonite is in the national dex dialga is in the original dex
No Pearl Is Better because palkia and dialga are the same put palkia has 1 bar more speed. Also because dialga has roar of time palkia has spaial rend roar of time does more damage but spacial rend does over half of roar of time and roar of time has to recharge
