Some suggestions
I have been a fan of Necromancer games ever since I discovered it. How about a little something old and a little something new? Do you recall the return to series of adventures? How about something like that instead of a reprinted update. If you do go with a reprinted update, can you add something like a repopulation section? You know when the easier levels get cleared and the PCs are returning for the harder portions, there is a section that details what takes the place of all those previously cleared areas. Granted, they will not immediately stock back up, but a guide of how fast and what types of monsters, etc. return would really be something that has not been done before (that I can recall). Do you remember the Bloodstone series? Something that incorporates mass combat would really be a nice change.
I see short adventure requests are very popular, can we have some that are centered around legendary weapons, the kind that grow with the PC? This could also fit with the lower level theme requests so they are more useful to PCs in the long run. Can we get a shot at destroying some evil societies or cults, or a mafia style gang that has grown powerful enough to hold an entire city (or at least a large town) in their thrall? One last idea, an adventure that the PCs participate in but is designed to have an end game they are too late for no matter how successful they are. A three act series that includes a blame period followed by a make it right ending? I do not recall anything that dire in design. Yes, PCs can fail in most any adventure, but to do everything right and still make it worse, at least initially, has not been done.
Necromancer games adventures have been a staple of my campaign for a very long time. What you have made and what you will make are what I like, so, please, get back to work
Not to mention a shameless plug for mythic and kingdom building material in future PFRPG products!
