Virtual Network drivers are defined per host and not per network (in
fact some of the technologies do not play together quite well, e.g.
iptables and ovswitch, when used in the same host)

You can however define different clusters with different network
technology  for the hosts, and then associated viertual networks to
each cluster (public network to cluster public) Note that VMs will not
be able to use both networks at the same time.

In your specific case, I think you can simply not set the VLAN
attribute in the public network template this will bypass the vlan
processing in 802.1Q and ovswith drivers

I'd recommend to take a look to the virtual appliance router, simply
add a virtual with a NIC in both networks
