Ok — mind officially blown — it never occurred to me to set shell thickness to a value less that the nozzle. 99% of my prints require two shells for strength, and since Cura doesn't seem to have a separate "number of shells" setting, I've always set shell thickness to 2x the nozzle diameter.
Re-ran the layers view in Cura and it would appear that .7 is the max shell width that will work, but will run a couple of tests this evening.
Thanks again for your help! I printed out 4 Raptor Reloaded hands ( http://www.thingiverse.com/thing:1033475 ) over the long weekend using the 0.6 nozzle and it saved me at least 2 hours per print at 130% scale. If I can get the .8 nozzle to print some of the "fiddly bits" such as the finger pins, I should be able to really cut down production time...
I think you got it in one. The "shell width" is more important than nozzle width so leave nozzle width at .8 and try shell width at .7, .6, .5, .4 and look at layer view and see where the vanes come back in. You can print with a .4mm nozzle down to about .3mm shell and you can print a .8mm nozzle down to about .6mm shell. But of course the quality will be reduced a little. It may appear to be a bit underextruded. Of course you can then bump up the flow but now you may have bad tolerances when you try to put the torque wrench tool together.
