A Tiktaalik for Placoderms

So many millions of years ago their was a lobe finned lung fish named tiktaalik that led to the evolution of all tetrapods and the diversity they hold today. And I wanna do that again, but instead of a bony fish, I wanna use a placoderm for the job. My intention in this is to have vertebrate creatures who are virtually indistinguishable from land arthropods. Yet even after all my research into fish I still cannot find my placoderm white whale, so I am asking y'all for some help.

Question

So my question is, what type of specific species placoderm would be best fit to crawl onto land?

Requirements

• Needs to be in the order arthrodira or a simular group that has self sharpening toothplates

• Need to have ray fins capable of evolving a form similar to a sea robbin, allowing for arthropod like legs and wings to evolve over time

• Need color vision(not sure if they all had this or just a select few?)

• Need to be omnivorous
