Yes, we do exactly that for a similar case, it works nicely. 

We use procmail to pipe the mail message through a script that calls
bin/rt looking for existing ticket with similar subjects. In our case
we want to merge the new message into the existing ticket, so we simply
alter the Subject header adding the RT ticket number, something like this:

my $rt_cli = '/usr/local/bin/rt';
my $timeout_cmd = '/usr/bin/timeout';

my $ticket_response = `$timeout_cmd 5 $rt_cli ls -i -t ticket "Subject like whatever-you-like"`;
if (my ($ticket) = $ticket_response =~ m!^ticket/(\d+)\s*!) {
      printf STDERR "Found existing RT-ticket $ticket\n" if $debug;
      $in_subject .= " [example.org #${ticket}]";
}

You could, of course ,skip the message altogether.
