Not sure what you mean here. If you use the wrong parameter name, the
compiler (or interpreter) will definitely complain.

If you have meta-knowledge that some pair of ROS Messages are in fact
convertible, you can write a node that translates one to the other, or
a subscriber that accepts both (on different topic names) and  does
the conversion into a common format for internal processing.

(My apologies: this discussion is more appropriate for answers.ros.org
