Need some hacks.
Need a hack. Fine, it is simple. Write your own shell! Standard shells are required to accept user-defined variable names that contain the 52 uppercase and lowercase letters (a-z, A-Z), the 10 digits (0-9) and underscore (_). The shell is allowed to accept other characters in user-defined names, but is not required to do so. I have not seen any standards conforming shell that accepts a period (.) in a user-defined variable name.

NAME
chsh - change your login shell SYNOPSIS
chsh [-s shell] [-l] [-u] [-v] [username] DESCRIPTION
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one. chsh is used to change local entries only. Use ypchsh, lchsh or any other implementation for non-local entries. OPTIONS
-s, --shell shell Specify your login shell. -l, --list-shells Print the list of shells listed in /etc/shells and exit. -u, --help Print a usage message and exit. -v, --version Print version information and exit. VALID SHELLS
chsh will accept the full pathname of any executable file on the system. However, it will issue a warning if the shell is not listed in the /etc/shells file. On the other hand, it can also be configured such that it will only accept shells listed in this file, unless you are root. EXIT STATUS
Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid. SEE ALSO
