NAT inside LAN Subnet to another inside LAN subnet before it goes over VPN on ASA

Hi All,

I have a branch location with an ASA 5505 (192.168.181.0/24). It has a site to site VPN to my data center. I need to reclaim the subnet of that branch location and allocate it to another location rather urgently (to make a /23 for a different site running out of IPs), but I can't do it properly (re-IP the branch site) due to Covid restrictions.

So I am wondering if for now there is a way I can NAT the LAN subnet (192.168.181.0/24) of that branch location to a different LAN subnet (i.e. 192.168.182.0/24) so that when it arrives at the data center over the VPN, it will be seen as 192.168.182.0/24 and not 192.168.181.0/24. I am willing to NAT on either side of the VPN to make this happen (branch or core). Any assistance is appreciated.
