[Question] Is there a possible way to give a trainer Pokemon in the non traditional way?

[CaiGuyCrafter]

So I'm creating a game where the end boss is in fact Red. However, not with his traditional team. I wanted to make it so that at the beginning of the game, you take a quiz that asks you what team YOU used in your playthrough of Pokemon Red, Blue, or Yellow. I was wondering if there was a way to make whatever choices you chose that of Red's Team. (I.E: say I played with a Charizard, Pikachu, Poliwrath, Jolteon, Snorlax, and Dragonite, he would have all of them on his team.) Would there be a way to do this, through scripting or something? Obviously the most common way to do this would be to go through and manually add his Pokémon in the Trained Data, but of course, going through every combination of all 151 Pokemon would be very tedious. If you've got any suggestions, let me know, thanks!
