Not sure if they'd fit - you'd have to stock up on 4 Heritage Druids and Nettle Sentinels to compensate. A couple maindeck Decays and more consistent Glimpses don't sound bad either way. A more Shardless-esque direction seems like a good place to go, anyway. And you'd have to slot in a land because even if Cradles suck, they're still the second land often enough.
