Ok I have no clue about how "tuned in" your wife is on beer lingo and terms. To me what she is asking for sounds like a train wreck. Did she mean she wants a lighter ale instead of pale ale? does she like wheat beers?
I will suggest this: I am about to keg this in a few days and so far it tastes freaking good and I normally am not a wheat beer person...

Another thing that most LHBS carry is heather tips also a good flower to brew with. If you have any lilacs about I have a GREAT Lilac honey orange wheat I designed for my wife. Recipe is here:

As for lavender...that was a SA Longshot winner but I have never brewed with it...
