I think the balance should be what happened with Intelligence in the Jezzek era.

- Early birds should benefit

- More production material needed (because production will be more plentiful and even cheaper to the point of buying everything possibly)

- Longer build times (except for those who already STARTED building if this can be helped)

- MORE int and gyms gains (that way already built homes will benefit day one)

certainly sounds like a good list to me. i think one thing I would add is possibly making it so construction materials are needed for upgrades not just the initial build would be cool.
