I am building a rather large rocket with wedge attached fins (think LOC Viper family). I currently use OpenRocket and I don't think it'll sim out that type of build. I only need CP, don't care about altitude etc.

Thoughts and help, please.
 
Just sim it as full diameter tubing. Your aft portion will have lower volume but more skin & interference drag.

This means your full diameter sim will be more pessimistic than actual, so when it sims stable you should be good.
