[40K] Could the Eldar 'fix' the Emperor's Door to the Webway?

It seems that the Door to the Webway beneath the Imperial Palace is constantly leaking, and one of the emperors 'jobs' is to make sure that it's all sealed so that Daemons don't swarm Holy Terra.

Could the Eldar, who are far better at manipulating webway portals, fix it? And make it sealed so thoroughly, that the emperor wouldn't have to pay attention to it anymore? Supposing he did, what would he use the otherwise-occupied psychic power for? Would sealing that webway gate cause any measurable effect on the Imperium as an entity?

No, most probably not. Eldar aren't that good with the Webway, they know how to build Webway gates and how to travel it, but thats all. The Webway was created by the Old Ones and since that antedeluvian era, no one, until that is, the Emperor, has been able to create a new portion of the Webway.
