Converting Star Wars d20 to D&D?

[Mirth]

I'm thinking of adding the races, classes, skills & some of the equipment from Star Wars d20 (original or revised) to a regular D&D campaign. Has anyone else done this already? Would the conversion be that difficult? I did google up this page:

Star_Wars_Conversion_Rules

Any critique of this guy's work?

Before you suggest it, I already have Dragonstar. I really want to find a simple way to convert the d20 stats in Star Wars to a 3E D&D campaign.

Thanks in advance for any advice or links
