A couple of items.
If the inner large bearing is still a good fit on the stub shaft and in the felt carrier the 1/16" wobble in the felt carrier is the internal movement in the bearing (magnified at the rim of the felt carrier).
The internal clearance in a bearing is the radial clearance - if the ball groove radius in the bearing rings is larger than the ball diameter then the rings can move axially even with a small internal clearance. This is not a problem with the outer ball bearing keeping the hub upright.
The hub housing design is made for a pair of ball bearings. If taper roller bearings were installed the housing would have a quite different design.
Austin Seven hubs have survived for 100 years - if you want a car with taper roller bearing hubs then buy a different car.
Most modern cars now have hub units which usually use ball bearings.
