I totally agree with you that Lelouch is Charles' successor. My own personal belief is that Charles somehow (Geass? V.V.?) knew the Lelouch was going to be his successor and all of this is to shape Lelouch into the perfect king. Suzaku was just an added and surprising bonus, but I still think Charles is merely using Suzaku to see how far he can really push Lelouch. My own theory is that at the end, Charles is going to declare Lelouch the king if Lelouch wins. Now THAT'S when I would be interested to see what Lelouch would do; he'd be given the world but by doing so would validate Britannia. It just seems so... Typical of a Darwinian system that the Britannian system seems to be and the fact that everything that goes wrong in Lelouch's life feels suspiciously planned out.
