More parts, more test fittings, more pondering... more pictures.
I went today to visit the wonderful mammals at Street Level Cycles. (Who are awesome, and to whom you should give money.) Poking around in the bins, I came across another, longer, taller, Kalloy dirt-drop-ish stem. This one's a 100mm, of unknown model. (95-11 is the only stamping that might be a model #.) I didn't find much else in the bin-o-bars that interested me, except a set of Scott AT-2 LF ultra-light MTB bars. (Which wouldn't probably look right on the Herc, but I figured I might need 'em, at least at first, and they were 5 bucks, so I bit.)
I did some mocking up, and... big diff!
With All-Rounders:
With drops:
And, just for fun, with the AT2s:
Cockpit views of each:
Much-a mo' betta!
I also found a 95mm OLD, 36-hole Normandie front hub... looks to be a 'Schwinn Approved' one.

It needs some love, but it's going to rain the next few days, and I haven't pulled a hub apart in many years... looking forward to it!
