I want those too.

This means we want control over columns in the completion view.

A brief look at Qt4 classes shows that we can implement the features we want
more easily without having complicated completion interface.
Qt4 uses model-view architecture therefore we can feed the text editor
with a model (subclass of QAbstractListModel). This way we will get control
over columns in completion view and would be able to display icons.
And also we can pass a delegate to paint completion items (subclass of 
QAbstractItemDelegate). Our delegate will of course know how to paint our
model. This way we can implement colored syntax highlighting.

That approach will require only one method:
KTextEditor::CodeCompletionInterface::showCompletion(QAbstractItemModel 
*completionModel, QAbstractItemDelegate *completionDelegate);
