Who might replace Mills?

Brad Mills' hometown paper, the Visalia Times-Delta, talked to Brad Mills yesterday to get his reaction to the changing direction of the franchise:

"It's an exciting time. We talked [Sunday night] about a lot of the rumors that were coming out. And I'll be heading to Houston on Wednesday to meet with [ownership] to discuss the future...

...It's just exciting to see them with a plan."

Should that plan not include Mills, which is - justifiably - going to be the decision of the new GM. Who might replace him? Well, Ken Rosenthal suggests that it's a strong possibility, and throws out Yankees bench coach (and Astros' Triple-A manager from 1991-2001) Tony Pena, and Bo Porter whom, strangely enough, AC suggested as a possibility for the Astros back in 2009. Porter lives in Houston, and has interviewed for the Marlins and Nationals managerial vacancies.
