I hope she's on board at least as a producer or maybe a cameo. She's got some solid production/directing chops, so it could be incredibly beneficial to have her on.

My money is on either her or Picardo being moderately involved. Carter is the obvious choice for the “General”, where Woolsey is a wonderful pick for civilian leadership as he saw significant growth over his character’s appearances. Smart money is on Hewlett appearing for at least a cameo, he’s more impressive in real life than his character, and I bet he’d jump at the chance to reprise a more mature version of his role.
