Faerie Conclave ties up blue mana during your main phase and doesn't allow you access to its mana out of the gate. Fish's free counters compensate for this to some degree, but a control deck needs

{U} on turn 2. Yes, they evade Moat and The Abyss, but that's not reason alone to include them. A control deck only needs a few (maybe 2-3) victory conditions.
For reference, here's a pretty standard Keeper manabase:
4x Polluted Delta
3x Tundra
3x Volcanic Island
3x Underground Sea
4x Wasteland
1x Strip Mine
1x Library of Alexandria
1x Island
6x SoLoMoxen (no Emerald)
This manabase only really works if you're running 4 Brainstorm, so keep that in mind.
At the risk of sounding unoriginal, I think your best bet would be to take the basic Keeper skeleton and add Humility to the mix, maybe cutting a Shaman to make room.
So, my anti-aggro Keeper would look something like:
26 mana (see above)
4x Counterspell
4x Force of Will
4x Brainstorm
2x Cunning Wish
2x Stifle
1x Ancestral Recall
1x Time Walk
1x Fact or Fiction
1x Mystical Tutor
2x Skeletal Scrying
1x Demonic Tutor
1x Yawgmoth's Will
1x Mind Twist
3x Decree of Justice
2x Swords to Plowshares
1x Balance
1x Humility
1x Gorilla Shaman
1x Fire/Ice
If aggro is really really heavy, I'd consider replacing the Skeletal Scrying with Impulse, but test the Scrying first. You might also consider tweaking the manabase to accomidate the

{W} of Humility's cc, maybe dropping a Volcanic for a City of Brass.
