Idea of pcsd is to be a basis for setting up all the layers of the cluster stack - so relying on the knet-layer would be an issue. That said it would of course be interesting - once knet-layer or whatever is setup - to be able to use redundancy for pcs. Excuse my ignorance if there is something available already. One thing that might be relatively easy to setup might be a virtual ethernet-connection via knet. Haven't played with that myself so others might be a better help to configure that - if pcs doesn't already have support for such a setup.
