I want to model a Geneva wheel in SimMechanics.
Is this possible? Any suggestions on how to model an intermittent contact of this sort are much appreciated.

You can utilize a point curve constraint to do this. I would model it like this:
1) Model the 'driver' Wheel directly, connect to ground via revolute
2) Model 'Driven' Wheel directly, connect to ground via revolute
3) connect the Driven wheel to the point sticking up from the Driver wheel via point curve constraint.
4) Design the pattern of the Driven wheel inside the point curve constraint.
This should be straightforward once you get the pattern figured out.
