I'm not an expert on the stratified tank model, but I am pretty sure that the IDD is not processed at runtime by more recent versions of E+. I believe it gets processed at compile time. So in general I don't think that will work any longer. In this particular case, just from looking at the IDD of the object, it looks like it would probably require source code modifications in order to handle a different number of nodes. So I think the ultimate answer to your question is that you may need to modify the source code to change the number of nodes. I'll try to verify by looking at the source code, will update this answer if I find something different.
