Midi signal flow questions

So Im still trying to figure out how to best setup midi with my current setup, i have an a4mk2 as the main clock, program change master and transport. The A4 is going into a Digitakt and a Digitone Keys, all three of them are playing great with each other (love this setup). I also have a squarp pyramid (used to control ios synths) that is recieving midi/clock, etc. from the DK.
So my idea is to connect/merge the midi din outputs of the pyramid to the midi inputs of the elektron boxes (without sending clock/transport) for automation/utilities /fun purposes, im looking into getting either a retrokits rk006 or a blokas midihub to use as the merger/router (and for all the fun extras) but im not completely comfortable with midi yet so id like to hear other peoples thoughts…
