Exactly half is hard to achieve. You have no way to know if you are getting that or 1/4 and 3/4. You just ASSume half each except with Method 2 and two batts you are pretty safe there getting about half each.
Method 3 requires all links to be equal or it doesn't come out right. The shunt and its single wire (however long) to battery neg adds to the length of the neg linkage. Good luck figuring out how much to shorten the two negs to make it all come out even again!
No need to re- drill everything, just junction as now and use "adapter wires" with a 3/8 at one end for connecting to the shunt.
Longer bolts will hold more lugs but eg, Mex says to avoid stacking if possible and go with buss bars. Some stacking is going to happen. It is worse with big lugs that are uneven, not flat. Hard to stack those. Stacking also requires rotating the wires away from one line up so the lugs can touch down flat. With many wires in the stack, you end up with a windmill of wires and can't get one around there because something is in the way of it sideways.
When you collect several thinner wires on a buss, the next single wire out from there has to be fat enough to carry the total amps of all those thinner wires.
Why can only one wire come off the shunt? It doesn't say that in the manual. Why can't I have two negative wires attached to the shunt, one to each battery. Electrically, this is no different than method 2, so I don't get why it's not allowed.
