Are you sure Global?

It would mean changing the class name in the roster file to match, but that would be easier than searching for so many PPL, TR or Type=103 entries in Campaign.RND.
Depends on the field requirements for "Type=" in the source code.
It may only insist on a 3 digit integer, though someone suggested in a different post that you could change the "Class=KSQ" to "Class=M35B".
If the type CAN be changed, you could leave the liners as 103, replace the "Class=PPL" with a blank line, and know you won't get a troop transport turn up doing 25 knots, or get a CTD.
Where "Class=TR" i'd have to put the new type number in, but subsequently either of the troop transport types would show, then just script in random convoy entries for the hospital ship and a Heavy Cruiser, to have a target i can't sink unless i want negative renown, balanced by a nice HC to aim at.
After that you could add as many liners, troops and hospital ships as you want and they're effectively all scripted.
I suppose only a Dev Team member could answer the question for sure.
Hopefully one of them will enlighten us
