Black tank leaking

The valve bodies have four bolts holding them together. If you take them all out (black and grey) it looks like you could get that stuff out of the way, now you have only a stub dropping directly through your floor. Enlarge the hole in the floor a bit with either the cut off jig saw blade previously mentioned or a Fein type multitool oscillating blade saw. I would then try to remove the flange from the tank. The glue joint is already cracked, so by wiggling it you might be able to complete the job. Now you have good access to everything to clean it up, and re-glue it.
At this point if it were ME, I might try to get a rubber no-hub connector between the tank and valve. That is a very short run, and stiffened by the grey water pipe. So any flex between plumbing and tank has to be taken by the glued flange connection - which must have contributed to its early fatigue. A rubber no-hub would give you some flexibility there to accommodate movement.
