What do you guys think of nll.ca and lll.ca domains? Any reseller value there? What if they have a homonym?

-For example, would 6at.ca be a good domain?
-what about the fact it can be read as bat.ca (e.g. a baseball or flying rodent website)?
-kat.ca a good dn? it's a homonym of cat. or hur.ca for her.ca?

Thanks a lot!
