while this is a well thought up DLC (my blog has a few of my ideas as well). when martin sealed oblivion, he made it so they couldnt be used as a way of attack. this is why the mythic Dawn coulnt open more. because the seals where in place again.

The gate to the shiering isles was diffrent, it was more of a door way or US to enter, this is why it stayed open.

If the gates could be used as a way to get to the realm the DLC was based around im sure it could work, but the Gates opening and closing would be a big deal
