Convert D3S to D2S?

[jschrauwen]

I have a set of euro (Ecode) D3S, Bixenon, AFS, headlights coming.
Before I install them, I'd like to try a conversion to D2S.
Aside from a slight modification (notching) of the D2S bulb base, can I assume it will fit into the existing D3S igniter?
If so, can I also use an after market 50/55W ballast with that igniter? Or would I need to replace the igniter to a D2S one?
If it's a case of replacing all 3 - D2S bulb, D2S igniter and D2S (55W) ballast, will that ballast still plug into my existing headlight harness?
My bottom line is I like achieve greater lumen output through the use of a higher wattage ballast but I'm not 100% sure of the inter - connectivity between the requisite components and existing headlight harness.

Won't you have to change the projector as well? FWIR, the D3 uses mercury free bulbs whilst D2s do not, not sure if that's also a (connection...) issue
