I had an idea for finding Susan in a future series of Doctor Who as a season long arc.
They hunt to find Susan and find a crashed TARDIS and a seemingly lifeless body nearby and they bring her onboard, does Sexy have a medical suite? They bring her onboard and revive her to find out that it's Susan who's ship crashed in the time war and they had to go almost to the edge of the known universe to find her because Sexy found anomalous readings from the fringes of deep space.
The Susan story isn't the whole series, they have other adventures just that's the arc running through the series.
