Different subnets on LAN to LAN VPN with L2 Bridge)

We are building a site to site VPN, though our router doesn't support IP routing. Therefore we have opted to using the L2 Bridge. My question is whether you can use this, and be able to give the different remote sites and the local site a different subnet such as 192.168.1.0/24 for the headquarter where the VPN server is and 192.168.2.0/24 for a remote location? As far as I understand this method makes the VPN server the DHCP server which can then give out IP addresses so this should be possible, right? Also, on the remote site I should disable the DHCP server as well, and then the VPN bridge will act like the DHCP server as well, and give out the IP addresses to the devices on the virtual hub? Please correct me if I misunderstand something. Thanks.

Imagine lan cable = it is the same as L2 bridge.
If it would work with lan then also with SE, if not => not
