I think he may have already done so, by way of Quirrelmort's reaction to Harry's statement that he wanted to use science.

Voldemort is scared of muggles. Quite reasonably so; despite Harry, there are enough of them that they'd very likely overtake the magic-users in a matter of decades on all useful fronts, and even now a conflict between muggles could squash the wizards like a bug.

Basically, I think he wants to

(a) Strengthen magical society to the point where they can stand up to the muggles. Harry might be helpful here, but there's a good chance their plans would conflict. Failing that..

(b) Get the hell off this rock.
