Mr Bassman, thanks for your kind offer, but the bass in question has bass guitar machine heads and it is making a real mess of whatever I put on at the moment. Have a set of 1/2 size 2nd hand spiros on the way and when I have got a new bridge set and all that I might put my present Honeys on from my DB and try a set of those solo Innovation ones tuned to concert pitch on my DB. I would not want to damage your D. I am thinking heat shrink on the Honeys at the machine head stress end to hold the wraps in, because I will need to snip them cos there is not much room on the machine heads. This would go for any 1/2 size strings as well.
