Separate subnet routers for clients in tailscale network

hello
I have several subnet routers, 2 of them have the same subnet address. I want to make some clients on the network use one router, and other clients use the second one.

I’m also considering doing something like NAT.
so that the subnet of the subnet router was 192.168.0.0/24, and for clients in tailscale it looked like 192.168.5.0/24

thanks for help
i am using translator, so translation maybe wrong
