It looks like it's starting to come together. 
YEP! Everything's back together. Just have the fairing skirt and outer fairing left to go... then an hour of polishing off all of the oily fingerprints.
Murphy DID finally show up last night, BTW... 
I thought I was being super careful in documenting all of the the wire positions, but made one error on the Twist Grip Sensor (TGS) connections. There are two little wire bundles that come from the TGS - both with one black, one red, and one white wire. One of the bundles is encased in yellow plastic, and the other is encased in black plastic. I had documented where the three wires go - but DIDN'T think to document
which wire bundle went in
which bank of the connector. Of course, I got them wrong. I put the wires from the black bundle where the wires from the yellow bundle should have gone, and vice-versa. 50-50 chance, and I lost... just like I always do in LA$ VEGA$. So, the bike would turn over, but wouldn't start. I unplugged the TGS connector, and the bike started up fine.
So I sez to myself, "Self, you got yer WIRES crossed!" 
Under 10-minute fix to pull the 6 TGS wires from the connector and put them in their proper places.
Not bad, as projects go! 
Haven't had time to take the bike out for a spin yet... but just sitting on it, the handgrips are now in the PERFECT position - no more stretching to reach them comfortably! They look beautiful, too... I love the fat, beefy look!

But the best thing was...
NO NEW LINES NEEDED! Plenty of room to go stop-to-stop with the stock ones!
Thanks for everyone's input, suggestions, and moral support!
Now where did I put that cigar???
