Not sure of the range on a 60.
But Prestwick seems to be a good option for the stop.
Based on the Great circle figures it is a benefit of around 70NM over Shannon.
Berlin - Shannon - Goose 2645 nm
EDDB - EINN 819 nm
EINN - CYYR 1826 nm
Berlin - Prestwick - Goose 2576 nm
EDDB - EGPK 667 nm
EGPK - CYYR 1909 nm
I hear really good things about the Ocean Sky FBO at Prestwick. They seem to specialise in tech stops. I hope to use them soon.
