[@Shiny Keldeo] I just don't think it would work, as the Empire would send Inquisitor's or Vader after something that big, also the clones would be weak and very old by this point. They could serve as commanders but not as soldier's due to aging. After this nearly 25 year's after the clone wars. Most were going to die in twenty so you can see how they were doomed, Rex was old man nine year's before the battle of Endor. The ship's couldn't have kept up repair's, remained hidden, and had enough crew to bring all vessel's back.

Perhaps he returned to Kamino with the genetic material of a Clone and had a new squad made but they would need training. It's not so much I don't want to have it's that it just couldn't manage, the resource's needed are extensive and costly. With eighty percent of those ship's crew being clone's most of the crew would be dead by the battle of Yavin and the rest of the clone's would be dead by Endor or at a point where they needed care and rest.
