Did anyone here get in on this?

IMO this pair is one of the most interesting objects I've ever seen, and it's not even cataloged. I predict it will show an AGN spectrum at high redshift. And if it does, you cannot say this is across the universe - this is a low surface brightness dwarf pair that are clearly part of some phenomenon that involves both equally - this is not a random encounter, but a fission of a galactic nucleus. The third member of the group is also extremely interesting, because it shows the bare nucleus glowing deep red with a ring-like structure around it and another nearby nuclear object.

Additionally, Hubble shows the galaxies as fairly blue in some regions, indicating a high rate of star formation. This is consistent with their mid-IR emission (lots of dust associated with star formation and chemical evolution) and the probable merger activity. I don't see any reason to believe there is any sort of relativistic ejection behavior of large-scale masses, which would be required for any part of the spectrum to show a high redshift. I would instead expect the far UV and X-ray spectra especially to show a blueshift of some kind, since both spirals are nearly face-on and the AGN jets would be probably be pointed towards us.
If someone feels inclined to write a proposal, it might get accepted, but not on a six meter like the MMT. Your best bet would be to request time on a one or two meter instrument, considering how bright the targets are.
