Unfortunately, the Keepers probably won't be of any use to Shepard. The Keepers were created by the Reapers for the purpose of activating the conduit and keeping the Citadel in good condition for future species. With the Conduit disabled, the Keepers now pose no threat, and exist only to maintain the Citadel. They do nothing else.
