Options are pretty much as follows

A) Leave the batteries out... Flat PRAM wierdness doesnt really affect most 68k's of that era.

Not sure I get this one, do you mean removing the batteries (cutting them from the board)?

The machine does not boot now, and it is likely because one battery is dead.

B ) Cut the existing pigtails really close to the old battery, lay somefoil or something under the area and carefully solder a normal battery to the pigtails from the old one... taking care to not apply too much heat to the battery for obvious reason.
normal batteries can be soldered even if they do not have soldering tips? Never tried that... But anyway, finding normal batteries that have 3V seams as complex as your third option.

C) Buy a cheap 1/2AA holder on eBay or where-ever and install it where the battery was. formerly suspended.
That was an option I was looking for. but 3V batteries are not cheap. I wonder if one could use 3.6V batteries, which is something I have enough of. 

D) Solder wires to the battery pads and run to an external holder mounted outside of the case or mount one elsewhere inside the case... personally this idea doesnt appeal to me, however there are a few propenents of the the external idea by virtue of it completely nullifying the chance of battery leaks destroying boards, which I can understand. It's just too messy and hackish for me.
Yea, agree with you, not what I'd choose first. But it could be possible to take standard AA battery size holder and put it on the HDD/floppy metal frame. Still internal, AA batteries and easily found and if they leak they will still be at a distance of the main board.
