NOBLOGREDIRECT with query string

I’ve got a multisite setup with subdomains. I also have wildcard subdomains configured on my DNS server. I want to set multisite so that the following will work:

Assuming domain1 does not exist, user goes to:

domain1.mymultisite.com/posts/some-post

The user is redirected to:

mymultisite.com/posts/some-post

So far, by using:

define( ‘NOBLOGREDIRECT’, ‘http://mymultisite.com’ );

I can get users redirected to the main domain.

Is it possible to have that setup as something like this:

define( ‘NOBLOGREDIRECT’, ‘http://mymultisite.com/$query_string’ );
