No, not really.  You could take any extension module and build it 
into the crash binary by adding it to the Makefile's CFILES and 
OBJECT_FILES lists, and adding a stanza to compile it.  But you 
would have to copy the help page data manually to help.c, and perhaps
tinker with the extension module source file if necessary if there are 
any namespace collisions.

If you don't want to hand-load extension modules, install them
in one of the appropriate locations, and then use "crash -x ..." 
to load them all automatically during initialization.

$ crash --help
...

  -x     
    Automatically load extension modules from a particular directory.
    The directory is determined by the following order of precedence:

    (1) the directory specified in the CRASH_EXTENSIONS shell 
        environment variable
    (2) /usr/lib64/crash/extensions  (64-bit  architectures)
    (3) /usr/lib/crash/extensions  (32-bit architectures)
    (4) the ./extensions subdirectory of the current directory
