Yes and no

Easy to do:
One non-Vlan + many vlan tagged 

If all the non-Vlan are also bridles then yes:
Either using iprout or alias IP

Alias IP can't be enslaved to a bridge thus if deciding to use alias IP then
can also do:
1 Non VLAN tagged + many tagged to many bridge-less non-tagged 

You probably can also create many iprout muti IP on a single bridge but not sure about the benefit of this - and still need verification.

Like you can see above more then necessary, may even need a third category :(

I tend to say yes. Cluster level.
PS. Network may have few attributes.

Management + VMs on one network Storage on the other 
Display + VMs + mamagement + storage (Small setup, with single network, Local storage DC)

Depending on the VM-networks tag if we have it.

Best way is to be add by vdsm as needed (When creating the first VM the uses it) but this raises some flows that not sure you want to have for 3.1 time frame
