How hard is to change the code to have a fourth battle theme?

P.S.
Before you ask, there are several soundtracks in the work that may take advantage of this addition. Both Inferno and Earth Defense, for example, will come out with totally exclusive soundtracks which may feature a possible fourth battle theme. In other words, this code change will not be a waste of time.

Looking at the code there appear to be a lot of assumptions that Battle track 3 is the final one. That would have to be changed in a way that didn't break existing soundtracks.

I couldn't see anything that made it impossible though, simply annoying.

EDIT : Taking another look at the code it does appear that someone has gone and spent a lot of time coding in a second parser for music table that could possibly cut the amount of work required in half. There's still a lot of work left with those assumptions though.
