On a DONEx only two of the NA segments are in A (DFW-BOS and BOS-SFO) and to add insult to injury, all the segments are on non wide-bodied aircraft so F is not going to be that comfortable.

I'm not sure I understand the bolded statement. There are 2 class flights between LGA-YYZ, YYZ-DFW, DFW-YVR, and YVR-DFW. Your DONE books into A on these flights so shouldn't you get F tier points in QF as with the BA scheme?
