Well, I didn't necessarily mean writing them out of the Avengers sequel--they could be occupied elsewhere in the plot, so introducing new members to the team would not force you to have 8-10 people in the room. Widow's secret mission (and Hawkeye in tow) could connect with the main plot and the team eventually. This is kind of like how Star Wars split up the team in ESB and ROTJ, and how X2 handled several threads at the same time.
