Actually you can make it work with !start too. Here's a little demo:

Open vim (not necessarily with latex-suite activated) and do:

let &mp = 'start gvim $*'
silent! make! %

you will need gvim.exe to be in your windows $PATH of course. You should
see another instance of gvim startup and attempt to reread the file....

The silent! is necessary because vim tries to redirect the output of
"!start gvim file" to some temp file and then parse it for errors.
Without the "silent!" it gives an error that the temp file cannot be
opened.

I got carried away and have already implemented this in CVS.

As of right now, I have made it substitute the substring
'{v:servername}' in &mp with v:servername. We could extend it to
something like:

    :function! Eval(expr)
    :    exec 'return '.a:expr
    :endfunction
    :let mp = substitute(&mp, '{\(.\{-}\)}', '\=Eval(submatch(1))', 'g')

This is also done in CVS. Should be uploading shortly.
