I like the popups, but I also really like the INX. I have wondered about using an Accord front clip a few times, but don't really have the equipment or experience to try it on any of my own 3rd gens. I would really like to see what you can come up with. I was at a Prelude meet last weekend, and one of the guys drives a converted USDM INX. I'm posting a couple pics of his car so maybe they can give you a little help with your conversion. Good luck and keep what few of us there are here updated. Sorry about the size, but I figured you might see more detail with the large pics...
He even added the INX center tail light and rear wiper.
