AD9116 DCLKIO CLKIN shared data bus and simultaneous synced output

We typically use a DAC with WRT_A, B lines but we want to switch to 1.8V logic.

We cannot find any DAC like AD9765 with silmutaneous update feature for 1.8V.

Therefore we are thinking about to use 6 AD9116 with a shared databus and sperate clk lines for each DAC.

Beside any fanout issues ...

Is it possible to delay and synchronize the output of all DAC with the CLKIN rising HIGH edge ?

How the retimer circuit comes into account and what is the expected latency. We have a window

of about 100ns for programming all.
