Users want to know how much something would cost if they would be using a different cost models (eg. with different per-unit price, or attributing cost based on RAM instead of CPU).

One possibility would be to allow multiple cost models to be assigned to a source, and set one of them as "reality" and the others as "simulation". After making their mind up, customers would be able to switch which one of the cost models should be used and remove the others.

How to make this play well with the cost explorer, cost reports, etc? To be brainstormed.
