I would suggest try the implementation of a wrapper script solution. In the ipc_info file make an entry for the common bshell file that does not point to bshell6.1 but to wrap_bshell. In the script you can start the bshell6.1 with your own options... I think the command line options from the client are not passed...
You have to test this because I am not really sure this will work out right for you.
