Why do you want to? Some designs use up a lot of logic, some a lot of memory and some a lot of multipliers. If you migrate to a different family these numbers may change because of differences in architecture. Converting everything to LEs is meaningless (why would I use LEs when I have memories/DSPs available).

You just list you project in N LEs, memories and DSP blocks, and you can carry it accross the family. The compiler will give you a % total used for each.
