My thoughts: definitely doable. What have you got at the moment?
I'm using a 400ml jug which I can get away with - i just tilt the jug to create a bit of depth (as opposed to keeping the jug level). I suspect it'd be more manageable with a 300ml jug.
It'll develop with time. For me, it was impossible with the duetto at first because it was too quick. I think the trick is to know where the sweet spot is and get it spot on from the start (introducing the right amount of air).
