No. Pokemon can't hold key items, and all of the needed items are key items.
Key items are impossible to trade or remove, except to Pokémon Colosseum.

no you can't let Pokemon hold key items
No, key items, of which the Super Rod is one, cannot be held by Pokemon.

Unduplicatable ItemsThe only Items you can't duplicate in Emerald are Mails, because you can't store a Pokemon holding Mail into a PC. You can't clone any Key Items either.
I thought that there was unlimited space for key items. How many items do you have and how many more key items do you need?
You cannot trade Key Items from other games to another because i you say, traded the Blue Orb from Saphire to Ruby, and went into The Cave Of Origin, then you would screw the game up, and possibly break it to being unusable!
Firstly, you have to go to Goldenrod City. Go on the very west of Goldenrod City where there is a really big building. That is called the GTS. You can trade there. *This answer has been approved and written by Wikia Lord.
As far as I know there is no code for key items.
Sorry, you can't trade key items to other players.
