I was wondering if I'd be hitting a limit - I'm almost up to that with one system

According to mentions in here in the past, you can with vswitch but not with "native' bridging/networking.

With the "native" networking, you can only run a tagged trunk between the Dom0 host and the external switch. Internally, each VLAN would need it's own bridge - and hence separate virtual NIC for the DomU
With vswitch, you can run a tagged virtual switch and a tagged trunk to the DomU.
I suggest you search the archives for previous discussions of vswitch. I vaguely recall that it didn't seem too complicated to do - but at the time it wasn't relevant to me and I didn't go further than following the discussions.
