The recipient domain is not known until deep into the SMTP session.

You don't need to split much, just the smtpd service. If it
is added to an existing Postfix instance it may be as simple as:
master.cf:
1.2.3.5:smtp inet n - n - - smtpd
-o { smtpd_milters = }
with suitable MX and A records to direct mail there.
This additional smtpd service for would have an empty smtpd_milters
setting, and perhaps a -o { name = value } override to reject mail
for other domains (relay_domains or access map).
(it's a bit more complicated if this service is implemented by a
separate Postfix instance, because you would have to make sure that
other Postfix instances don't listen on a wildcard IP address because
they would receive mail for 1.2.3.5 when that service is down).
