Absolutely so.
I don't know if you came across this article:

Unfortunately it is in French, but can be translated with Alta Vista's Babelfish. Makes for very interesting reading. I suspect that the sabre in question must have been an experimental one, because all the 19th century military sabres that I have seen, had edge geometries very similar to that of Japanese swords.
Deep fullers can reduce the friction encountered, but that to me is something of an overstated argument because on sabres, the COP usually falls right where the fuller ends.
Here are some measurements that I have made on two of my sabres:
Ames 1862 :Edge angle at COP: 22deg At 3"from pt 17.68deg Blade thickness at COP 5.5mm and 3"from pt 3.5mm
Brit 1854 :Edge angle at COP: 23.53deg At 3"from pt:20.6deg. Blade thickness at COP 5mm and at 3"from pt 4mm
Perhaps you could tell us how these geometries compare with that of Japanese blades. Unfortunately, I do not have one at the moment.
Cheers
Chris
