V studio 20 and external mixer

I've just ordered a v studio 20 from a uk dealer for £100, which is a great deal. I write my own material, some of which is acoustic based. The v studio only has one external xlr mic input whereas I'd like to use 2 mic's to record the acoustic. I have been looking at the behringer xenyx 802 and was thinking of putting 2 mics through the mixer and connecting it to the L & R input on the vs 20. Has anyone tried this? I'm assuming it should work no problem?

Any advice would be most appreciated.

Thank you
