Sweet thanks! p-5 will be my next bike! That's exactly what I want to do!

Grill's link pretty much covered it already, but the P5 fork uses a standard steerer tube so any standard fork or integrated handlebar can be mounted.

I bought a used P5-6 that came without a handlebar, so I set it up with 3T Ventus II bar. I made myself a "beard" by cutting up an old plastic shampoo bottle that was the right shape, then spray painted matt black. It mounts to the underside of the base bar with magnets. It takes a very close look to see that the beard not original, and cost me nothing other than a bit of time and effort!
