I'm going to assume that you want to change the default location of the
startup file, since bash already allows you to specify an alternate file
with command line options.

Changing the default startup file is easy, but it depends on how much
source code editing you want to do.  If you are ok with modifying source
(and I imagine you are, given the scope of your project), take a look at
shell.c:

194:static char *bashrc_file = "~/.bashrc";
1768:  bashrc_file = "~/.bashrc";

Modify these two lines to contain the pathname you want and recompile.
