No. MX lookups happen late in the process, when the message is in the
"hands" of the delivery agent. Postfix has an active queue, so message
transport/nexthop needs to be known in the queue manager.

If these all reach a common IP address via a variety of names:
Use "iptables" or similar, to destination NAT
192.0.2.1:25 to 192.0.2.2:25.
assuming 192.0.2.1 is the natural MX host, and 192.0.2.2 is the
one you want instead.
If these all use a common MX hostname, override the IP address of that
name in your local DNS resolver.
