As Gallifrey isn't actually trapped in a bubble of slow time I don't think there's a connection like you suggest. The war is in a "time lock" and Galifrey is in a pocket universe.
However, there are connections between Galifrey and Krikket. As detailed in the linked quiestion Did the Doctor inspire Slartibartfast?, Adams wrote Doctor Who and the Krikketmen, which ended up being adapted into Doctor Who's sixteenth season (The Key to Time) and of course Life the Universe and Everything. Krikket was never equated with Galifrey. Instead I believe it was the Time Lords who imprisoned Krikket.
Adams was also the script editor for season seventeen, writingand wrote Shada which was adapted into Dirk Gentley's Holistic Detective Agency.
