Shared SSL - Redirect https to http

I've spent over and hour searching and couldn't find this question, so help will be appreciated!

I have a shared SSL on a single IP. Assuming the SSL is for aaa.com:

https://www.bbb.com will redirect to aaa.com and throw SSL errors (while still showing bbb.com in the address bar)

This becomes a problem because Google is now indexing https://www.bbb.com for some reason which I don't want.


Question:

Is there a way to just redirect https://www.bbb.com to http://www.bbb.com OR https://www.bbb.com to https://www.aaa.com? .htaccess doesn't seem to work.

I just want to avoid the nasty "untrusted site" message.

 

In other words, it isn't possible - correct?

I guess I may look into getting another IP then.
