Yes, option b is fairly easy.  I arbitrarily called the option --noinit, 
and it suppresses loading of maxima-init.  maxima-init is searched in 
the normal paths used by file_search, but the loading of maxima-init 
might happen too early for you to change file_search paths.

Is having --noinit good enough for you?

Perhaps it would make sense for maxima to have a site-init file located 
in the same directory hierarchy as the installed maxima.  This could be 
similar to how sh works, which loads /etc/profile first, then the user's 
.profile.  I didn't investigate that, but it seems straightforward to do 
that.  I guess you would also want a --no-site-init option too.
