Large Mod Compilation (Maybe)

I am thinking of putting together a fairly extensive mod compilation, but I first wanted to know how the community feels about something like that. Some examples would be Oscuro's Oblivion Overhaul. The main reason I ask, is because I don't often see mods that do similar for Morrowind.
I'm sure there are more relevant questions, but it's late and I'm getting tired. So please, voice any and all opinions/questions on the matter.
Thanks in advance for any input.
- Do you feel a large mod compilation is acceptable?
- How do you feel original authors rights should be handled?
- If unable to contact a mod author, do you feel the mod should or should not be included?
