An update to @WWC's answer that will help the target action be able to find the view it needs.

public AController : Controller
{
     public ActionResult Bar(BarViewModel vm)
     {
          FooViewModel fooVm = MakeFooVM(vm);
          var bController = new BController();
          var bControllerContext = new ControllerContext(this.ControllerContext.RequestContext, bController);
          // update route so action can find the (partial)view
          bControllerContext.RouteData.Values["controller"] = "B";
          bController.ControllerContext = bControllerContext;
          return bController.Foo(fooVm);
     }
}
