How is this scenario?

User connects via http and gets a virtual host by name.

The http virtual host redirects to a SSL server running on a unique port
for the unique name on the SSL cert on that port.  (You'll need DNS
records that point to the same address.)

So, http://site1.com/ ends up at https://site1.com:4000,
http://site2.com/ goes to https://site2.com:4001/, etc.

I think it'd work.

By the way, here's what I use to redirect to SSL.  I sorta cheat since I
use a PHP script for the hard part.  You might be able to do it with
mod_rewrite if you like that better.

<VirtualHost *:80>
SSLEngine off
DirectoryIndex /lib/redirect-to-secure.php
AliasMatch ^/.* /home/httpd/ti/lib/redirect-to-secure.php

Here's redirect-to-secure.php:
$location = "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
        "Location: $location",
<a href="<?php echo $location ?>"><?php echo $location ?></a>
