What's the best way to have a different theme for an aliased site: e.g.:

I have foo.com and its alias stage.foo.com.
foo.com uses "baz" as the theme, stage.foo.com should use "baz_stage" as the theme.

As implied, my use case is for internal testing, so I'm happy to rewrite/override the theme variable on every page from a custom module (or settings.php etc).

I tried 

if ($_SERVER['HTTP_HOST'] == "stage.foo.com") {
    $conf = array('theme_default' => 'baz_stage');
}

in settings.php but this didn't work - presumably because it's getting rewritten later on by domain_conf.

Just as more information:

This code:

if (isset($_SERVER['HTTP_HOST'])) {
	   if (stristr($_SERVER['HTTP_HOST'],"stage")) {
					$conf['theme_default'] = 'baz_stage';
		} 
}

seems to work for "site 0", but not for any other site.

e.g. site 0 is foobar.com and stage.foobar.com shows the stage theme. However, site 5, which is foo.com doesn't show the stage theme for stage.foo.com.

I've tried altering the weight of Domain Theme in /admin/build/domain/settings but that hasn't made any difference, and I've tried overriding $GLOBALS['conf']['theme_default'] using hook_init.

Is there anything like domain_conf_variable_set which I can call which won't update the database?

OK, after a bit of rooting around Domain Theme, it looks like it's easiest to override $custom_theme, so now having this in hook_init of my custom module works:

	if (isset($_SERVER['HTTP_HOST'])) {
	   if (stristr($_SERVER['HTTP_HOST'],"stage")) {
					$GLOBALS['custom_theme'] = 'bar_stage';
		} 
	}

Hopefully this is a problem-free way of doing things.
