Pretty much -
According to my good friend Al Phillips of the TVRRM - with whom I spent last Monday afternoon
and evening discussing steam locomotives in general and the AC-9's in particular - they were very
closely based on the S.P.'s highly successful Cab-Forwards, but out of necessity turned around to
facilitate the use of coal as fuel.
Unlike all of the other classes of sixteen-drivered articulateds on the S.P., the AC-9's were built by Lima rather than Baldwin, so I presume the S.P. passed along their specs for the AC-6, AC-7 and AC-8 Cab-Forward 4-8-8-2's when the Cab-Rearward AC-9's were being designed. Per Al, they are quite a bit heavier than the B&O 2-8-8-4's, but nowhere near as massive as the DM&IR Yellowstones.

p.s. The photo posted above is from a recent scan of what is apparently a print of a company builder's photo that once hung in Lima's western sales office in Portland, Oregon. The original is so large - roughly 9½"x22" - that I had to scan it in two parts, the front turned 180° from the back, and then the two scans merged. The Epson V600 scanner that I purchased a few months ago based on the recommendations of JBWX and others seems to do a pretty good job - see if you can tell from this close-up where the separate scans of the front and the back were joined:
