Marc Lavallée, Eric Benjamin, and I put together a Trifield (three speaker stereo) plugin and demo'ed it a Burning Amp last fall. It is hosted at
https://bitbucket.org/ajheller/trifield/overview It is written in Faust so can be compiled for a number of different hosts, but we provide precompiled VST plugins for Windows and MacOS in the download folder. There are also some plots that use Gerzon velocity and energy localization vectors (rV and rE) to analyze, +/-45 deg stereo vs Trifield vs +/- 30 deg stereo that shed some light on why "the +/- 30 deg stereo triangle" works well.
