Well, this is at least 90% as good as the original: Privateer Gemini gold
. There are a couple of spots that can be a little buggy, but I didn't have any trouble on my play-through.
I actually think the combat is a little better in the remake than in the original. For instance, in the original, I remember being able to beat a Kamekh capital ship with a fully decked out Centurion just by sitting in front of it and holding the fire button. Not so much the case in the remake ;). Also, Gothri heavy fighters seemed much more of a challenge to me.
Gemini Gold is a pretty good (and free) remake that I too recommend.
But I still would LOVE to see Privateer on GoG, and the entire Wing Commander series for that matter.
