It depends on the MTA.  I believe Sendmail is smart enough to notice that
both MX hosts have the same IP address, and send the mail over one SMTP
session.

Well, the downsides are you'd use up 50 or more IP addresses (which
may or may not be a concern for you), and you'd use more bandwidth.
If you're a very large site, you'd probably annoy people who send mail
to lots of your domains (though most of those people are spammers
anyway.)

As a means of avoiding stream_by_domain, it's a good idea.
