Was Dr. Hiriluk part of the Roger Pirates?

In chapter 967 we see the Roger Pirates tracked down the remaining three Road Poneglyphs to Fish-Man Island, Wano Country, and Zou.

Oden continued adventuring with the Roger Pirates until they reached the final island, where Roger found the treasure left behind by Joy Boy.

As I reread the chapter, this panel caught my attention.

The character highlighted in red has a certain resemblance with Dr. Hiriluk. Is it possible that Hiriluk joined the Roger Pirates at some point?
