If the wheat is there for head retention, then the hops should cover you. You should be able to cut it out without an issue.
Personally, If I were trying to keep it light I'd do the bulk of it as Pils and then either 20-25% Vienna, 15-20% Munich, or 5-7% Melanoiden/Aromatic. To me, once you start to layer a few base malts in a lager it starts to creep towards Märzen/Bock kind of maltiness. That's not necessarily a bad thing on its own, but it may end up hiding the hops a bit.
I guess it's all about what you're looking for in your finished beer.
