FWIW, a lot of places make a "Summer Bitter" version of their Pale Ale, doing just as you said - 100% base malt and hopping accordingly. It's already been said, but the hop regiment will really catagorize it for you. It seems like you are falling somewhere between a blonde and a Pale Ale - if it is malt forward, call it a blonde, if it is hop forward, call it a PA. It may be tough to enter it into a competition with success, but it would be a great beer to have on hand for consumption during the warmer months.
I just had Brooklyn's Summer Ale, so this concept of a 100% Base Malt "Summer Bitter" is fresh in my mind.
