Interesting object overlapping or merged or something else?

Eliptical galaxy overlapping or merged with a blue ring galaxy ? Or something else ?

From this image alone, I don’t think it would be possible to say. Detailed 2D analysis - using GALFIT, say - may help, but I suspect that only spectroscopy (what are the redshifts of the blue things? the central elliptical? galaxy? etc) could resolve such questions.
