I want to convert my 84 300d to a four head light system, good idea?

I am going to upgrade the 7 inch lights to cibie H4. I am also planning on changing out the fog lights and replacing them with 5.75 H4. I plan on running the low beams (5.75) with the pull out fog light switch and relaying the high beam to go on with the 7 inch high beams.

Does this jive with most of you?

Why am I doing it?
I want alot of light without the hassle or risk of high wattage bulbs.

Has anyone else done this?

thanks folks
