The best solution for content past GoD is to implement it yourself. Custom content is always fun and you can literally do almost anything you can code.
Some of the devs were/are working on a hugh update for the main database. You can read about it at the following:

It is possible to level past 89 but that is the cut off for the current source code. It does not occur because of a bug it occurs because the exp value exceeds the limit of the variable used for exp. With some mods to the source you can level past 89 with no problems. My private server goes to level 254 before leveling by exp is halted. Another individual in the community was able to level past 65000. There is a link to some of this some where on this site but I don't feel like finding it right now.
