yes, like most things it's probably doable, if someone wanted to do the hacking work.  
but besides the other problems mentioned, none of the nubus macs have a powerful 
enough processor for os x to beat out an old sinclair machine....  of course if you've 
added a g3 card, you might have the processing power, but those cards are already 
grossly hampered by the bus and memory bandwidth, and an os like os x does a lot of 
swapping, particularly if you don't have a lot of real ram so it would be further 
hampered by the bus bandwidth for that as well as the drive overhead and slowness, 
which is pretty slow with the built in scsi on most macs, largely because using a 25 
pin connector was a bad idea.  it doesn't have enough ground lines and that limits the 
bandwidth you can pump through the cables.  it wasn't a problem on the first macs, as 
they couldn't handle much more anyway, but i wouldn't try it for an os that swaps 
without a fast scsi card.  that means you'd have to make it boot.  the kernel would 
have to be modified and added to, and you'd probably have to write drivers for the 
nubus bus as well as the particular cards you're using.  bad idea, it would make more 
sense to use that time at a minimum wage job and save up for a faster machine, which 
between the earnings and deflation of now new but soon old computers would allow you 
to buy an early g3 or g4 machine and do things reasonably properly, i.e. matching the 
os to the limits of the machine it's on.  even with a fast processor card with a lot 
of cache, the memory, nubus, and drive bandwidth would severely degrade it.  if you 
want to run a different os on a nubus mac, look into the many command line and 
xwindows unix variants like netbsd, openbsd, linux, etc.  though i'm still trying to 
get netbsd to boot myself (i'm close, the next time i play with it it will work since 
i've since read more about it, truly sparse directions that come with netbsd).
