Quite the reverse - you need to move the strap button about 1-2" from the neck joint towards the blade. Also moving the tail button up to the left hand curve of the butt of the bass will help it balance almost vertically. I had built a custom axe and found those to be the ideal locations for absolutely no neck dive.

all that matters is that in playing position, the closer the neck-side button is towards the headstock as measured strictly horizontally (i.e., regardless of how low or high it sits on the bass, like you were going by a yardstick laying on the floor under the bass) the less neck-dive.
if that marked location puts the button horizontally closer to the neck than having it at the end of the top horn (meaning if the bass is held up at a pretty steep angle), it could work, i guess.
+1 to moving the back button forward a little, for the same reason.
