Making a good ganja is not so easy for an untrained person. I personally tried a few times with not very convincing results. Moreover in your case, since the blade is in good conditions, the ganja should have about the same appearance.
You could try to find out a scrap keris with a good ganja and adapt it to your blade, if necessary. This is a method I used a couple of times.
Alternatively you could look for loose ganjas in the Swap Forum. I bet in Java is plenty of such parts.
