A. Not in theory.
C. If you redirect with a 301, then the old domain should eventually drop out.
it may be perceived as sketchy to now use it to redirect traffic to a different site
Possible. Google won't take into account what your intentions are (or even stop to figure them out) but generally a 301 redirect won't get you into trouble.
I have no idea what you're going for though, I can't imagine a situation where I'd do something like this, unless I had a court order to shut down the first site or something.
