Allow the Kihraxz to take the 'Heavy Scyk' titles.
The Kihraxz really doesn't have a role right now, which almost fits because in the lore it was designed as a general purpose fighter. However, it was also stated to have been designed modular, so that a large number of variants could be made by customers.
This fix would both fit with the lore, and give the Kihraxz something to do. It beefs it up a little, which it definitely needs, and gives it the option to either become a cannon-bearing gunboat, or carry two different missiles, or make use of extra munitions, giving it a role.
Even with this, its not going to be setting the world on fire, but it might make it at least somewhat usable.
