Mini roundabout for Newlands Park/Westbourne Road near Penge East station

Recently near Petts Wood station there has been a similar junction where the main flow of traffic is round the corner, whilst being a crossroads, which has been changed to a mini roundabout which slows the traffic more and makes it easier for cyclists. http://osm.org/go/0EEBtsaNj-?m

I'm wondering if the same can happen here.
