I have not done this personally but I know a guy who did. In fact our local homebrew club the Manty Malters had a SMASH beer "competition" where we each did a SMASH (Single Malt and Single Hop) beer. I made a Bohemian pilsner with Saaz that turned out too fruity, must have fermented a little too warm. But anyway..... the one my friend made with 100% Vienna and Tettnanger hops was the standout awesomest beer of all that won the comp. Everyone loved the complex toasty malt. The Maris Otter beer took second I believe. Somewhat personal preference, I suppose, but even so, we certainly proved, at least to ourselves in our club, that a fantastic beer can be made with all Vienna and no specialty malts.
