Not possible with VLANs, but you can do it with floating SelfIP addresses, Virtual Addresses, SNAT Addresses. Essentially, as soon as one IP address is announced (L2 ARP) by your Standby unit, you're operating a partial Active-Active setup.

 

If you want to try it out, create traffic-group-2; move some of the SelfIP addresses from traffic-group-1 to traffic-group-2, and then force traffic-group-2 to Standby. More details in a manual below.
