I think i've read something about the plan in the original version being something like that, but the setup to there would definitively be better
Code Geass's tale is a sad one, no one expected it to be the success it was so of course Sunrise wanted to milk the hell out of it, problem is that CG aired at like 1:30AM or something like that, so Sunrise changed the slot to 6:00 PM and advertised the show like all hell, and since there would be a lot of newcomers to it they changed everything so they could follow it more easily, what we know for fact is that there would be no 1 year time skip and Lelouch would actually win the duel against Suzaku, for the rest of it all we can only guess, there's so much loose end from the first season... I still can't believe they scrapped Jupiter entirely
The funny part is that as much as Sunrise wanted it to be the new Gundam, it still only got half the ratings Gundam 00 got which aired just a season before and after
