I would like to convert a continuous rotation into two 180° intermittent rotations. A standard Geneva drive layout can not do this, is there any variation of a Geneva drive that can do this?

Above is an example of a 4 slot Geneva drive capable of four 90° intermittent rotations.

It's simpler to add a 1:2 ratio gear ration on the output of the geneva drive to get your 180° rotation per 90° of the intermittent
