I'd suggest, from a technical standpoint, the following changes:

1. Reduction in downforce by 50%.

2. Return to slick tires.

3. Increase tire size by 25%.

Those 3 changes would (probably) allow the cars to run similar lap times to today, but would enable more passing. By decreasing aerodynamic grip, while increasing mechanical grip, cars could follow closer down the straights - get a tow, and pull off a pass under braking.

These changes could reduce the number of times that we see a driver close up on a competetor by 1 sec per lap, and then not be able to get past him.
