Yes. This is the simplest attack you could do. Don't worry about cracking the hash. Attack the hash by replacing one the existing hash with a known hash.
If you find the location of the predefined hashes in the program, create a new MD5 hash of any string (say blablabla) and replace one of the hashes in the existing predefined hashes with the created hash and you are done. It should work unless there are any other checks that are based on the serial number.
If you would like to share the executable privately for patching, let me know and I'll see if I can help to patch it.
