One approach could be to have, for example, six separate lists that cover a range of conditions, and then have a starting view that would redirect to one of those lists based on conditions.

The only way I can think of doing something like this would be to use the API and externally process those tasks in some way. That's what I have done for some different scenarios.

For example I have one script that changes the priority of a task based on how many subtasks I've completed in a day, and then it no longer appears on my several smart lists. The following day, it gets updated and is back on the list.
