Screw-in bulb or double ended bulb for a 150w metal halide ballast?

[Mykiss]

I've got a 150 watt ballast for a metal halide fixture and it's originally for a 'screw-in' bulb. The only thing is that there's not a lot of 150 watt screw-in bulbs rated for ~14000K

My question is, can I remove the screw-in socket and replace it with an HQI double ended sockets?

The reason I want them to be double ended is that there's a lot more double ended bulbs with ~14000K rating in the 150 watt.

Thanks
