that's understandable.
for such purposes, I think you can try .class file modification method:
try BCEL's helloify example at: http://bcel.sourceforge.net/ - then [examples].
this is working fine for me, both to modify bean .class file itself and also
container (my case->JRun) generated stub files (even after deployment).
funky :) way to do this might be http://www.aspectj.org (AspectJ),
but this seems to be a bit unstable for very complicated code (as far as
last time I have tried it was so; might be different today).
(but it's very FUN to try - I recommend this:))

what I'm doing right now is a bit like proxy server for EJB servers
(although an application dependant one; ...doing generic EJB proxy
server might be challenging/interesting but it's currently beyond my
scope/knowledge -- does someone know of anything).
my program right now enumerates the beans deployed on the target server
and then generates stubs for all of the beans found there (for itself).
this part is working but the resulting files look a bit cluttered; and
I'd rather like to have a more beautiful looking method... (any idea?)

so far it appears like, I'm stuck with the static file generation scheme :p
