if you are serious, or just waiting for a miracle, no one is going to give you some "magic" amp settings with the rig you have that will get you where you want to go. if they could, then you probably would not be here asking. So if you are actually serious about searching for the sound, changes need to be made. You seem to have done some research on what is needed, but i think what you are asking for is a shortcut that does not exist. There are compromises, if you want to continue to be less then 100%, if not changes need to be made. I listed below some guitar changes that need to happen to put you at a good base.
Jerry late 70's
Dual sound's instead of super 2's
Alembic Blaster, not for the boost but it is the period correct buffer for maintaing your high end by isolating cable capacitance.
OBEL, to remove the additionally buffered tone sucking pedals you have in your chain. Also, period correct.
Wired like tiger, the wolf schematic is from after jerry played it in the 90's and was never played live wired like that.
That is just a start, i know you stated you wanted to get close without "buying every piece", but there are some things you will need to attend to also with your amp. A good tech can decipher the post alembic mods and apply them to your reissue, which you need to get done if you are indeed serious.
These will help in the eventual turn to preamping the twin and using a solid state amp(mac)
But if you just want to turn knobs, middle, right, middle, left and a splash of reverb.

"Without a doubt, the quality of your instrument will effect your tone, and any pickups, effects, amps, and microphones used along the way will also have an impact on the sound waves."~Cameron Mizell
