Honestly, I'd do the starter now and pitch everything, just leaving off the cold crash step, unless it's a really big starter. I usually decant off my starter beer too, but have been known to toss everything in for a short notice brew.
Edit: looks like beergolf beat me to it!
I can't be arsed to keep up this list of what's in the fermenters, but hey, check out the cool brewery I own!
