Honestly I wouldn't try to encourage/suggest doing this with any new functionality. If current mods don't support the ideas, you might as well toss the ideas.
The impression I got from your comments was that there were already mods that caused blocks to disintegrate under certain circumstances. That alone, if it exists, would allow you to assemble this pack with the core motifs intact.
New functionality is the entire point. If you don't integrate new stuff you only have rehashes of what currently exists. If the only thing that differentiates this pack from, say, AS2, is the fact that islands are generated and you cannot fly, then what's the hook... nothing new, just redo AS2 with a new self imposed restriction. You need something new to make it stand out.
No, only some of the concepts are reused, the disintegration concept is a new one as far as I know.
If this conversation sparks a mod maker to create that mod that makes this pack possible, cool! If someone that has a better knowledge of existing Mods, can figure out a way to tune those mods to this functionality, cool!
My exposure to mods is limited to what I have played, major packs, that's about it. there are more mods I haven't played than ones I have. I know that my knowledge of what is currently possible vs. what has yet to be created is extremely limited. Which leads back to the point of the thread; exposing the concepts that people would like to see, to the people that can make it happen. (which is not me)
