I know some people aren't keen on static initiative scores, but equally some (myself included) really don't like the slowing down that occurs from re-rolling initiative every round.
Here's one option: roll initiative once at the start of the combat. Every round, add each characters' initiative bonus to their initiative score.
Eventually the fastest characters will end up going first, and the slowest characters will end up going last. What this doesn't do is allow a character the random opportunity of suddenly reacting faster than their opponents, but for that there is Delaying / Readying.
Alternative 2: for a Move action, you can add your Initiative bonus to your current initiative score.
Alternative 3: As Alternative 2, but make it a Combat Feat.
