The DX Hub has 1x GX/gigaACE port for connection to a console. This carries 128×128 channels at 96kHz.
The hub then effectively breaks this out into 4x DX ports, each of which is 32×32 channels at 96kHz for connection to expanders.
The GX4816 also has a GX/gigaACE port for connection to the console, so no, it is not possible to connect this to a DX Hub.
However!
The GX4816 is actually like an expander with a smaller DX Hub built-in, or maybe a DX Hub with analogue I/O added… You have onboard sockets, plus 2x DX ports.
So you can lose the DX Hub from the setup, have one connection to the console to the GX4816, then connect each of your DX32’s to the DX ports.

Hope this helps.
