In short, yes. Being Rogue/Vigilante means you can go from Paragon to Rogue Isles at will without much trouble.
As long as you don't take part in any of the morality-decision missions (the ones that upon completion put you Villain or Hero), you're good to go. This means if you're a Rogue, you can do Positron Taskforces (if I recall right, there was no restriction). So just be careful how you do your Newspaper missions, you can do morality missions fine but that final one you want to steer clear of and/or delete.
