Even if we did get a crossover that pulled some of the characters from Voyager out of the AQ and forward in time, that doesn't mean that the regular series wouldn't continue on at it's own pace. They could keep things vague with maybe just a few hints for future books. I know they jumped ahead and stayed there with DS9, but there's nothing saying that would have to be the case with Voyager.
Logic would dictate that the voyager novels will follow the same path as the DS9 novels.
What's good for the goose....
