Don't expect better performance or things like that. I'd only do it if
you need features that are not included in the Ubuntu kernels or if youz
like to play around a bit.
Better don't do it on a important system.

I'm doing it and had no problems so far. But of course you are on your
own than if you have problems. 

Keep the original Ubuntu kernel as a backup so you can boot it in case
your own causes problems.

It's usually safe to remove hardware drivers you don't need. Don't
remove things you don't understand.

Maybe you need to apply some patches to get the same features as the
Ubuntu kernel.
