multiple domains inside of one blog

I have hescominsoon.com active now. I would like to do one of two things:

1. either setup MU to have hescominsoon.com as one blog and kb3vvt.com and kb3vvt.net on one site inside of MU.
or
2. Have the kb3vvt’s redirect to the ham radio section of WP.

Which if these is doable? I don’t not want to have to run another instance of wp for this as i already have two blogs i maintain(eccmd.com is my business blog).
