Ah, good ol' Runecraft. That was the most helpful mod ever when I built the underground dome on my SMP server, uh, two years ago? Yeah, two years ago. Didn't know it still existed.
As far as getting it into a single player world, the short answer is no, you can't.
I mean, running a local server, and then connecting only 1 client that way, you could kinda fake single player, I guess. And if you are running BukkitForge you might, maybe, get a few of the FTB mods running. But the chances of getting an entire FTB pack running is effectively zero. Not all mods support BukkitForge 100% and vice versa. And, not to be harsh, but you'd have to be more tech savvy than I think you are to even make the attempt.
So, no, you can't.
