Site to Site VPN and use another WAN IP to NAT to LAN IP

My client is a supplier for a large US automaker. The automaker requires every suppliers to crate a S2S VPN for its auto sequencing process. Currently my client uses Cisco ASA, and the setup goes like this.

Now, I am replacing the ASA5505 with Meraki MX75, but I cannot find a way to do the S2S VPN NAT on the Meraki. I have tried the ‘Site to Site VPN Translation’ https://documentation.meraki.com/MX/Site-to-site_VPN/Using_Site-to-site_VPN_Translation, but when I tried to translate 210.1.xx.48/28 to 192.168.200.51, it gives me the ‘overlapping VPN subnet ’error. And I think this ‘Site to Site VPN Translation’ does not serve my purpose because the MX will translate all the WAN subnet (I need to only translate one IP). Can anyone shed me some light? Thanks,

If the ASA 5505 did the job, I would replace it with a Firepower 1010 (running either FTD or ASA image) for this use case. The MX is quite limited when it comes to extranet VPNs.

Thanks Karstenl, but the client has already bought the MX with 5 year Adv Sec license 🙂
In fact, the client has been moving to Meraki Full stack, last year they replaced old Switch and AP to Meraki MS, and MR. and this last piece to replace is the MX.
So, I just want to confirm that MX is incapable of doing this 'S2S VPN another WAN IP NAT'? 
by the way, is there a specific term we call this kind of NAT?
Thanks again,

with Cisco it is often referred Policy-NAT.

Unfortunately it is not possible to do this with MX.

I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

Please, if this post was useful, leave your kudos and mark it as solved.

I end up keeping this 'Policy-NAT VPN' with Cisco ASA, and move everything else to Meraki MX 

Thanks everyone for the suggestion.
