I have two ideas in mind. Both would have unfolded over the last six or so episodes.
The first idea would have been for the crew to never have found any further shortcuts home. Their journey took the 35 years or so projected. Each episode in the arc would take place a certain amount of time later than the last with the passage of time increasing from a few months to years to ultimately 35 years when the crew returns home. Each episode would show how the crew and life on VOY had changed. Then the last three episodes would be all about the aftermath and their lives now.
My second idea would have centered around Unimatrix Zero with the BOrg civil war leading to a galactic scale battle with one front in the Alpha Quadrant and Admiral Paris/Barclay and the second in the Delta Quadrant where the crew works with the rebel Borg as well as races like 8472 who have a stake in toppling the Borg. It would lead to Janeway's actual assimilation and sacrifice to destroy the Queen. In the end, Axum provides the crew a series of coils to get home. And the finale would also examine the aftermath to their return home.
