Googleplex, looking for a launcher experience. Can you help me?

Hey guys,

been just scanning through the monthly "show me your homescreen" thread and found some icon packs that were very neat. However, I really love the Google Now integration and the basic workflow of the Google Now Launcher (Google Experience Launcher) so here's my question:

Is there a launcher that:

a) Works and behaves very similar to the Google Now Launcher,

b) Offers support for icon packs and

c) lets me access Google Now on the most left page of the homescreen?

Many thanks in advance to everyone who has an idea on how to achieve this, I think others might be thankful for such a solution too.
