Using Analog Switch ICs?

The datasheets seldom show replacement parts when the part gets obsolete. The last update on the DS is usually just the obsolete info.
If not too old one can often still find a general info page for the part at the manufacturer, where they usually also show a replacement. Other wise just search for a new part - quite often new parts keep the pin-out if there are older parts they can replace.
The 4016 presumably has less charge injection (and maybe typical leakage). So the 4066 is not always better. The 4066 and similar are cheap parts from the logic series. For higher requirements there are higher specs special switches, like DG211 and many similar.
