Having tracked down that quote, I also see he alludes to having killed Athena, but that's still light on detail.
No he doesn't at all! You even posted the quote! Read it!
That's not proof for your point, that's a metaphor. Hephaistos held Athena's beliefs which grew in the part of Lahabrea's soul that was in agreement with her. Hephaistos was NOT (fully or in part) Athena's soul, he was Athena's emotions, memories, beliefs and experiences.
Now let me take your position for a second, I think I would interpret it like this:
After the merger, part of Athena's literal soul was still attached to Lahabrea and possibly vice versa as well. That's the part of Athena that he then rid himself of to create Hephaistos.
That's however mere conjecture based on what I consider to be a misinterpretation of metaphorical language.
