Will an Alivio M405 or M410 (3x8) brake/shifter work with a Tiagra derailleur and side pull brake?

Here's the project: I have an '02 Specialized Allez I want to make into an upright w/new head and flat bar. But I don't know if the Alivio shifters/brakes will work with existing Tiagra derailleur/brakes. I'm hoping someone might be able to point me in the right direction.

I have a Sirrus but it's a larger frame. Since I already have an '05 Allez and haven't been able to sell the '02 I thought I'd turn that compact frame into a hybrid.

June - Project cancelled, bike sold. Bought a Roubaix SL3 Expert.
