Once you add enough distance, you start to over-tension the belt, and you risk failure that way. Once you remove enough distance, you risk ratcheting.

5 thou or less added seems like it would be fine.

Using GT2 belts with HTD pulleys is slightly stronger than HTD / HTD, but weaker than GT2 / GT2. I don't think you need to do this - if your belt strength is marginal enough for this to make the difference you don't have a big enough safety factor.

Remember, 15mm wide for 24T pulleys in a drivetrain.
