There is a simple collection of my mods for the X4: Foundations, which improves and is some cases fixes the issues with Lost Ships Replacement feature was introduced in version 7.50.
This feature allows the fleet to request a replacement ship if a ship is lost during the execution of an order. The replacement ship will be requested automatically, and the fleet will continue to execute the order.

• Lost Ship Replacement - Phantom Crew Revealer
  Unfortunately, the replacement ship will come with only a captain/pilot in place. In reality, there are some other crew members on the ship. This extension fixes this issue and reveals these "phantom" crew members on the ship.
  
• Lost Ship Replacement - Filters for the Shipyards
  This extension allows you to exclude some Shipyards from the list of available for the Lost Ship Replacement.
  Filtering can be made by the ship class, i.e. per S, M, L, XL ships.
  
• Lost Ship Replacement - Enabler
  However, even if you enable the Lost Ships Replacement feature for a fleet, the replacement ship will not be requested during the execution of the "default" orders. The replacement ship will only be requested after restarting the order.
  This extension fixes this issue for some of them:
  
  • Patrol
    
  • Police
    
  • Protect Position
    
  • Protect Ship
    
  • Protect Station
• Lost Ship Replacement - Better than Old
  The original replacement ship will have the same outfit/loadout as the lost ship and will be requested automatically.
  But what if you want to have a better replacement ship? At least from the loadout point of view.
  This extension can do it for you!
