Run UBIFS on top of IDE mode NAND disk?

[Subodh Nijsure]

Hi,
 
I have board with 4GB NAND memory chip, it is configured to operate in IDE
mode. And currently I am creating ext3 file-system on it. 
This chip also have on-board controller that does wear-levelling, ECC so the
quesitons are:
 
Can I (Should I) run UBIFS on of it and gain more of wear-levelling or its
not worth it?
