With all due respect, you don't need to have tried it to know it is a bad idea.

All you need to know is a bit about electricity.

You cannot mix and match your HID components. They are only designed to run at the specified wattage.

The best you can hope for is to DRAMATICALLY shorten your bulb life... to mere HOURS rather than the expected year or more of daily use.

The worst you can hope for is a fire.

So with all due respect, don't ask a question and then wait until someone gives you the answer you want to hear... listen to the people who are telling you SAFETY FIRST.
