I think I'd move the sense wire. I would expect that to give the least issues over time. Creating a new junction point would only cause me lots of headaches. Tricking the inverter to give higher output will work, if not combined with wets, as Bill correctly pointed out; if you have those. Switching wets to agm will bring the charge requirements closer together, so that may need to be your next upgrade. I have wet chassis with gel house and leave them combined essentially 100% of the time. Other than one wet cell crapping out, everything else has worked well for the given technology.
