Not directly. ImageEn provides a set of tools that you can use to compose other effects, and you surely can compose a lomo-like effect.
For example you could merge two layers using a blend operation: one layer will be the image to process and another could be a painted ellipse to make the border more darken:
Note: intensities and smooth are deliberately increased to show the effect.
