Not quite as rushed now. All this is for 4 magnet poles.
I don't believe the 1/8 x 1/16" will do much at all. The 1/16" is too thin. The 1/8" will have a lot of losses and are hard to get together to amount to much surface area. If you decide to go with the tiny magnets, leave the factory wires and reconnect them as in my diagram in the link I posted above. I have a feeling you will need all the turns you can get. They can be changed later if need be.
The 1.25 X .562 X .125 will have a very large effective airgap. It may help with the cogging, but the output will suffer. And the magnets are SO wide it may cause cogging... I'm not sure about that one.
The 1/4 x 1/4 should be OK if all 9 are used.
I don't think there is a common flat magnet much better suited to this than a 3/4 x 3/4" and 5/16 or 3/8" thick.
I only have a few in various stages of completion, or lack there of. Pure 'Jerry Rig' works best on most with factory wiring. Delta output is less. Star output is lowest for 12V because of the resistance (do not be fooled by the high open voltages).
An amp at 12V is easy with the factory wire and fan blade, given some Good Wind.
If I ever get around to rewinding one, I'm going to try 130 turns per coil (tooth), test it, and connect it Jerry Rig or Star to suit my needs. A single degaussing coil from a TV or 15" monitor would be plenty of #20 or #21 wire.
Do not get too carried away with 'better neos'. It can cause cogging in these. My best guess is the flux leaks to the other coil laminations after the intended lamination is past saturation.

Having access to good machines, it could be worth looking for a motor like this...
It is almost the same size, but far thicker, and with much heavier wire (2.5 ohms per coil by the meter). 1/6 HP 115VAC 6.2A.
It may be a decent cantidate for the 1.25 X .562 X .125 magnets, standing up and stacked a few deep. It is from a vent fan of some kind. Semi common.
Stuck rotor with 4 curved magnets, but it shows some of the good stuff.

Show me some progress and I'll send you some great magnets for one.
