Yes it is.
(I am currently doing exactly that on a system with 30+ VLAN interfaces.)
It is my (mis)understanding that the --vlan-id is used to match traffic
to/from a specific tagged VLAN on the /raw/ interface. (I don't know
for sure b/c I never match on the raw interface. I always use the VLAN
sub-interface.)
