Solo Gen IV Catch 'em All

So here's my idea. Using 3 ds systems, complete a Gen IV Catch 'em All solo. How does this work? Here's my idea of rules. Just like the regular Gen IV catch 'em all, complete the national dex in Diamond, Pearl, platinum, Heartgold, and Soulsilver to the best of my ability (484 pokemon). This also means playing a gen 3 GBA game to migrate up the Regi's. Now, in a normal Gen IV Catch 'em All, you would have 5 people, each playing one game at the same time. Instead, only I will play, but here's the catch. I can play up to three games at the same time. Because I have 3 ds systems, but one doesn't have a capture card though, the one without a capture card can only be used for the purposes of trading (If you see one screen for trading, you don't need to see another.) So basically I have a 3ds with a capture card, an original ds with a capture card, and a ds lite which can only be used for trading.

Other than that, I can't do any glitches, and the only manips that will be done are for starters and lottery ID manips. This means no manipping rare pokemon, or feebas for that matter....

I don't know if I would do this in a more casual setting, or as a full speedrun yet (My guess for speedrun would be it taking between 5-7 days.) However, I may start routing it out soon. And when i say routing, I mean making a very loose route. Most of this will be improvised. I know this is informal,but figured I'd put my idea out there in some written form.
