For what it is worth, the Novatec/Dimension/Ben's (etc). hub, which is very similar to the Formula hub, comes with a hollow axle, which could be converted to QR simply by sawing the axle to the right length. Novatec actually makes that hub with a QR axle, but I don't know anyone who sells it that way. See here...

I don't know if that same axle will work with a Formula hub, but the info may be helpful. If the axle is not available separately, and the formula and dimension axles are interchangable, you could buy a Dimension/Bens front hub, swap axles, then ebay the Dimension/Bens hub.
Alternatively, you could buy a Dimension/Bens hub and relace your wheel with it. The flanges are similar enough that you could reuse your spokes.
Why do you want a QR front wheel anyway?
