If you are determined to do this (and you really shouldn't) you should set your into nation with this string tuned to D.
The set that is closest to good for this is .112 .079 .059 .043 .031 or there-abouts.
The Strings am using at this time is .105,.80,.65,.45,.30 - with this I think since am Useing DR Neon. Am thinking the overall wight that my Bass is under right now is 214.5 lbs maybe a little less. This was based on D'addario Tension Chart
Am thinking of something like this for it .110, .85, .70, .50, .35 this would what my Bass is under if its with this set up 253.8 lbs, less thats too heavy. Am not sure how many Pounds this would add or take away. Overall its a 39.3 lbs diffenet. This was based on D'addario Tension Chart
