It's possible, but as Corona pointed out, it's not at all secure. The best that you can hope for is to deter a lazy and incompetent adversary, someone who doesn't want to think through the code and who doesn't know enough to enable tracing (set -x) on your script.

You can't even do this in C or assembly language. If the instructions are there, they can be decoded.

It would probably be much more constructive if you described what you're defending against.
