Question regarding poles on neodymic ring magnets.
(OP)
Will it be possible to find some of these with the poles inside and outside the rings instead of the flat sides of the rings?

RE: Question regarding poles on neodymic ring magnets.
A few manufacturers do this, here is an example of one (see page 7):

It is usually less efficient than a std magnet with pole pieces.

Maybe you need to step back and look at your proposed magnet and its pole pieces and see how you could do this with an axially oriented magnet and different pole pieces.
This geometry is difficult in RE materials (where powder must be oriented in the compaction tooling) and usually results in much lower properties.
In materials that develop orientation in heat treatment such as Alnico you can create a wide range of orientations (such as 6 pole rings).

janeeriksen: What grade of Neodymium Iron Boron do you need for your application?

The pieces were ground and epoxied together, not as mechanically strong as a single piece, but full magnetic properties.
