Yes the Ironcross is a Mackie model Kitbashed from Khaliban/'P81 models. The Connie (secondary hull) is Khaliban, the excelisor top is P81s' and Mackie/Atheorhaven neck. Textures are from the orginal artists, appleied bu Mackie/Atheorhaven and then modified by me. That was the short version.
The Galahad is a kitbash by Mackie on P81s' models for the X-Class ships for OP (they were his prototypes, before Paramount selected one). The textures are in pretty bad shape (heavily Blurred) and would require allot of work it is possible but i doubt I would do it more than one. So if I do decide to do it you had better suggest a colour shceme to me before I start orthat is probably the way it will stay.
Right now I am finishing up the Yellow and FPF Ironcross variants and need to get a StarFleet Presidents Connie and Excel not to mention the FPF versions. I can take a look at it after that, and see if it is something I want to do.
