Daenerys is delusional - Aegon won the Throne by Right of Conquest, and he is also someone the realm 'knows'. Daenerys on the other hand is a complete outsider no one knows, and even if she would have all of Dorne by her side it wouldn't be enough to win against the rest of Westeros, and especially when she only has one dragon (and as long as Aegon won't be stupid enough to chain his, his will be bigger)
