I don't see it happening any soon because only thing the Shura (Parliament) is concerned is with rights of Qatari Sponsors.

In 2008, when Parliament had sent labor laws modifications to Emir for approval, they suggested to INCREASE the ban from 2 to 5 years as a measure to protect the rights of Sponsors. Thanks GOD that Emir refused the proposal and kept the ban to 2 years. Govt is not at all interested in reducing the ban as it does not serve them any benefit.
