Has anyone upgraded the xenon bulbs in their AFLs ?

I'm looking at changing the bulbs to the 6000K units and have found These units.

They claim to be a hybrid between D1S and D1R and will work in either.

How long does the job take and will in involve removing the headlights? If so, is there any issues with alignment when you put them back?

As far as 6000k goes, that is a high as you can go without getting into blue lights.
