I was wondering about this for a while.
You have all inspired me.

I present a possibly simpler way.

Flag projects to denote 'Big Rocks'
Flag tasks to denote 'Most Important Tasks'

Once in the context view, tasks from 'big rock' projects will appear with a transparent flag.
Tasks that are MITs will appear with an solid red flag.

They can be made to appear on their own with the flag filter setting.

Sounds like a good idea and I will test it. Anyone else?
