Juniper QFX port VLAN statistics via SNMP - is it possible?

I'll just leave the solution here in case that anybody else needs it:

Firewall rule:
firewall {
     family ethernet-switching {
         filter vlan-counters {
             interface-specific;
             term vlan-14 {
                 from {
                     dot1q-tag 14;
                 }
                 then {
                     accept;
                     count vlan-14;
                 }
             }
             term vlan-571 {
                 from {
                     dot1q-tag 571;
                 }
                 then {
                     accept;
                     count vlan-571;
                 }
             }
             term vlan-572 {
                 from {
                     dot1q-tag 572;
                 }
                 then {
                     accept;
                     count vlan-572;
                 }
             }
             term default {
                 then accept;
             }
         }
     }
}

Applying it:
set interfaces ae0.0 family ethernet-switching filter input 
vlan-counters
set interfaces ae0.0 family ethernet-switching filter output 
vlan-counters

Checking the show firewall output:
Filter: vlan-counters-ae1.0-i
Counters:
Name                                                Bytes              
Packets
vlan-14-ae1.0-i                                   7474383                
  8504
vlan-571-ae1.0-i                                        0                
     0
vlan-572-ae1.0-i                                        0                
     0

Filter: vlan-counters-ae1.0-o
Counters:
Name                                                Bytes              
Packets
vlan-14-ae1.0-o                                   2651051                
  4919
vlan-571-ae1.0-o                                  2057853                
14731
vlan-572-ae1.0-o                                      644                
    10

Now, SNMP get:
$ snmpget -v2c -cpublic 10.1.2.3 
'JUNIPER-FIREWALL-MIB::jnxFWCounterByteCount."vlan-counters-ae1.0-o"."vlan-571-ae1.0-o".counter
JUNIPER-FIREWALL-MIB::jnxFWCounterByteCount."vlan-counters-ae1.0-o"."vlan-571-ae1.0-o".counter 
= Counter64: 298848

Thanks Luke Guillory for the solution!
