Not the way that you seem to want.  inodes specifically do not contain any file naming references.  This is intentional.  It's how hard links on Unix work (and cross-linked files on FAT... er... don't).  What you need to do is traverse the raw directory data for the filesystem looking for the inode you want and matching it to one or more file names.  Yes, this will be slow.  No, there's no way around it.  You're stuck doing an exhaustive search if you want to go backwards.
