Little silicone plugs are available where they sell powedercoat stuff.
Those would probably be the ideal.
Might not hurt to plug the low end and backfill with fresh brake fluid then plug the high end so there's not any air trapped in there to help corrosion along while it sits.
The old hoses will have a hard weave liner insdie them making them very difficult to clamp shut. ('crush' would be more the term actually)
Of course the other alternative would be to raplace the hardlines at the same time as the soft so you're positive everything about the rebuild is fresh, sparkly and clean.
