An acquihire can be a great way to build marketable skills outside of actually writing the code. I'd try negotiating a mutually agreeable path that allows you to move into management after some period of time.

From what I understand (no disrespect meant, just anecdotal accounts), it's more difficult to remain hired as a coder after 40 (especially with kids). Getting some management experience on your resume will help later in life.
