Yea, folks do it all the time. You just use a clean, neutral ale yeast, and ferment as cool as you can.
For example Rogue dead guy ALE, is a Maibock "styled" ale. Meaning maibocks are traditionally lagers, but in rogue's case it uses ale yeast (pacman).
And a lot of starter kits (like cooper's or brewer's best) aren't true lagers either, the grainbill is, but knowing that new brewers usually can't lager yet, use a neutral ale yeast.
Like my snazzy new avatar? Get Sons of Zymurgy swag, here, and brew with the best.
