What she did not take into account was Merlin and Lancelot, with Merlin she expected he would either be killed by the Dorocha, stopped by Arthur or simply not go through the veil, Lancelot she did not know and therefore would have been a surprise to her.

As plans to kill Arthur go, it was ridiculously over-elaborate. She had a spy in the castle who could easily have seen to it that he was poisoned or something like that.

If Arthur died, Agravaine was to be Regent and to take the crown himself if/when Uther died. However, even as Regent, it was unlikely to go down well if he turned the Crown over to Morgana, unless the plan was for him to "discover" that she'd been enchanted all along, was totally innocent of all wrong doing and, as Uther's only surviving child, the rightful heir to the throne... and even then it would be an incredibly long shot. Even if he tried to make a case that it was better for Camelot in the long run to accept Morgana as Queen than to have her as an enemy, it'd be a very hard sell.

As the plan was for Arthur to sacrifice himself to close the Veil, Morgana wouldn't have been able to use the Dorocha as a bargaining chip to secure the throne for herself.
