Only ask because I also play some guitar and often use a capo, and would be a lot easier for me to use a capo on bass if I am am recording bass lines, save transposing everything. To be honest I wouldn't have thought a guitar capo would be strong enough to fret bass strings.
Only reason I thought of it seen several photos of Paul McCartney using a Capo on his Ric
