Yes, you can use the PRINCE mode for this (functionality originating in
the hashcat project).

Instead of "--wordlist=", use "--prince=".  It will combine words, but
it will not alter the individual words - so you need to have uppercase
versions of "shin" and "shino" in your input wordlist file.

You can also use some other options on top of PRINCE.  This includes the
various "--prince-*" options modifying its behavior, and also "--rules"
and "--dupe-suppression".

Separately, I recommend that you leave our password.lst file as-is, and
put your custom words into a new file with a name not clashing with
those included in JtR.  One reason for this is so that you can use "git
pull" (followed by a rebuild) to update to newer revisions of JtR code.
