mr. nog dies to a dilemma and downloads mr brunt. he joins the attempting away team ?

There's no location specified for the download so it has to be somewhere Mr. Brunt could ordinarily report -- which normally means to a facility (so not part of the mission attempt).

If you can find a way to report Mr. Brunt to your attempting crew or Away Team (e.g., Temporal Micro-Wormhole for a space attempt) then I believe he will join the attempt.
