I think it's fine for the DS9R to jump forward five years to be in line with the post-destiny time frame, but only as long as those intervening years are not glossed over. Due to the heavily-serialised aspect of DS9 both on screen and on page, the stories tend to be better told in small periods of time.
Not to disrespect Christie Golden, and I seriously mean that, but her post-finale Voyager books were not the best and it made sense for the post-finale series to be pushed forward. But there was material there to push it forward and the gap was only two years. With the DS9R we have no material to use between '77 and '80 and then the Borg/Destiny stuff up to '82. Since very few people want to see another Borg novel, this is leaves very little established to work with unless we have a long drawn-out Ascendant conflict, which doesn't jibe with the rest of the DS9R.
If we were to have a fork in the road for the DS9R, with half the books--or a trilogy or miniseries--charting those missing five years while the other half concentrate on the post-Destiny time frame, that's fine. I just don't want to see the New Frontier route where we jumped ahead three years and were told that they would be covered, only to find that thus far they haven't been. The DS9R is my favourite series, even after the twists and turns it's taken into the MU, but I don't want it to lose that top spot just because one editor decides that her predecessor's plan just won't work after what she's done with the rest of the universe (no offence intended to Margaret, I loved the Destiny arc) and then when she is unfairly ousted (regardless of the current state of the economy, but that's a whole 'nother story) will the next person to fill her shoes continue with the jump or stay with the past, or a mixture of the two?
I can't help but think if Marco was still there, he would have found a way to bridge the gap, but as I'm sure Christopher or David or someone will no doubt correct me if I'm wrong (as I usually am on these things), Marco may well have gone along with Margaret and we'd still be in this same position.
Here's to the future of the DS9R, whatever it may bring.
I'll be here until the very end.
