Daisy chaining hall effect sensors

[okw]

I'm daisy chaining a row of hall effect sensors. At the moment 27 sensors spaced out on a 130mm length (but I could loose or add a few sensors to make use of all inputs on an existing IC).
I would like to see more than a 0 or 1 from the exact sensor where the magnet is. So if the magnet is between two sensors I would like an analoge value from all surrounding sensors, so I can calculate position with high resolution.
I was thinking about a multiplexer, like 4067. Will this be a good choice, or are there better MUX alternatives, or even better techniques?
What frequency with reliable position can I expect from this setup?
