This. Would not be an everyday lineup, but to shake things up once a week I would like to see Markakis lead off and Jones in the two hole. I would give Roberts a rest, even if Buck wants to keep him in the lineup, and bat him in the nine hole. This would be my solution to his sub package with izzy in the lineup as well.
As far as your lineup, we both prefer the alternation and I like having the speed on the back end. While marching orders are in the 5 to 7 slot, it really only impacts the first go around. I tend to think Hardy and Jones can clear the paths, but also provide speed for the top of the order to drive in runs. Better balance in lineup to maximize output with your lineup over the second and third at bats.
