I am looking for a way to control several devices from a few meters away from each other, usiig a Raspberry PI (Wired!). (i.e. Servos) I would like to use 1-3 signal lines to be able to control hundreds of servos, individually, similarly to the Individually addressable LED Strips. My fist thought was a multiplexer, however I've only seen addressable multiplexers with maybe 16 input addresses. They also tend to have many outputs, whereas I would like 1, maybe 2. I would like the cost to be as low as possible. My current solutions are ~$0.80 each output to achieve this, however i would like to go cheaper.

(My current solution uses a 2 8-bit shift registers, dip switch, and a digital 8-bit comparator, and some AND-gates) This gives me 2 data inputs (in/clock), 2^8 Addresses, 8 outputs. This is exactly what i need, however this is spreads out across multiple chips, any solutions to condense this down?

Thanks!
