It's really no big deal to mount a root fs with JFFS2 on NAND FLASH (8 bit
buswidth). It works right out of the box, if you take the preliminaries into
concern (see http://www.linux-mtd.infradead.org/tech/nand.html)
It is used in production systems.

If your deadline is so tight and your capacities are so restricted, you could
consider to sponsor one of the volunteer experts. This would speed up
development rapidly. :)

See above. :)
