The issue is the link count in the inode for the parent directory. Each
subdirectory has a ".." link that points back to the parent, and the
maximum link count for an inode in an EXT2 or EXT3 filesystem is 32000.
A directory begins life with a link count of 2, so there is a hard limit
of 31998 subdirectories.
The limit for reiserfs is larger (max unsigned integer - 1000), so that
would avoid the problem. Yes, you can certainly create a reiserfs
filesystem and mount it without having to reformat other filesystems on
your machine. You will lose whatever data was on the partition that
you reformat.
