Of course it's possible, but the real question is, is there any advantage to justify using anything other than water?
Just run your steam plant off water, and if you want to use low boiling point liquid, just set the boiling point of water to about 40C.
To do this, you need a condenser, cooled to the point where the low pressure turbine stages exhaust into a pretty good vacuum (once air has been purged out of the system) and you'll find that allows you to use the energy in the steam down to about 40C.
Exact numbers relating temperature and pressure were traditionally published as "steam tables".
Using ammonia instead, you certainly wouldn't want to exhaust it to atmosphere, so either approach requires a condenser. Having added that, there is not much to be gained from moving away from water.
There may still be a thermodynamic advantage to ammonia (or diethyl ether) if it has much less latent heat of vaporisation than water; I can't comment on that.
