"How about machining a Ford ring and pinion to fit the Packard pieces?"
Unlikely that the Hypoid offset (how much lower the pinion centerline is than the axle centerline) would be the same.
There is also the problem of physical size. The Ford has a 9" OD ring gear and the Packard is larger.
These two considerations makes getting the Ford pinion in the right place in the Packard housing difficult to say the least.

On edit:
I just scaled the 7th/8th Series rear axle breakdown on page 113 of the parts book. I know the straight part of the axle shaft is 1.750" because I have a 740/745 axle in the shop.
Using this figure I find the ring gear to be 12 1/2" OD or thereabouts.
I would not of thought it was quite that large.
