It's fundamentally impossible.  The concepts are orthogonal.  

There are four separate ways of getting access to a block device driver.
You can use a block device in /dev.  You can use a raw IO device in 
/dev/raw/ if you have a kernel which supports it.  You can use the swap
code to access it as a swap partition.  Or, finally, you can use the
filesystem code to access it as a filesystem.  The same device driver
is used underneath in each case.

Running ext2 over a character mode device simply doesn't make sense:
it's the same device driver underneath, the behaviour wouldn't be
any different.
