well, not necessarily the nacelles from any of the Enterprise evolutions. There are tons more star ships with different designs. I was thinking about maybe the nacelles from the Dauntless http://www.starshipmodeler.com/trek/ss_dauntless_WarpNacelles.jpg
I want it to have a very distinct look about it, im perfectly fine with it not looking EXACTLY like a recognizer. The more strange and unique it looks, the better.
And for the landing gear (or feat of the regonizer) i was thinking about sanding down the bottom ends of the nacelles, and cementing them to the feet of this gundam model http://fudoushin.files.wordpress.com/2009/04/img_2643.jpg with the tips of the boots pointing outward if that makes sense.
