Nope, the WAN and LAN networks need to use different, non-overlapping network ranges. The only automated way to get the LAN prefix is to ask the ISP via DHCPv6-PD.
Routing in v6 is exactly the same as in v4. If your ISP gives you 203.0.113.42/24 on the WAN, you can't turn around and use other parts of 203.0.113.x on the LAN. The only difference is that in v6 you actually get a routed prefix, and that DHCPv6-PD exists to automate it.
