I believe your request was misunderstood by TK Liew, please verify the scenario below:
Site A: you have 5 VLans, 100,200,300,400,500
Site B: you have 3 Vlans , 100,200,300
You can create a Layer 2 Speedfusion (you need one peplink device per location) and from there you can pass all your VLANs so your two sites will communicate with each other.
You can use WAN1 for the ADSL connection and WAN2 for your fiber. You can load balance your connections for high availability or throughput.
Please confirm that this is the scenario you are looking for and let us know for more details. Note that when selecting devices take a look at the Speedfusion throughput for each model.
