Guidance on how to combine 2 separate models/mounts?

I’m looking at adding a Blink Camera mount to my A1 for better live monitoring, but would like to also incorporate a cable guide. I’ve seen models for both, but the virtually mount in the same spot. is there a way to combine the 2? Where can I try and make my own version of the 2? I’m willing to put in the time…just need a little guidance!!

Thanks!!

something like what’s described here?
