For the first, I'd say probably to avoid that if you can. It'd be much safer to take the originals, scale them up twice as large, and then edit that. The graphics are all more or less the same anyway.
And as for the second question, I'd say if it's been less than 24h then edit, otherwise I *guess* you could post again.
