I think I do. I don't know the table semantics, but I think I have the general idea of what I'd need to do to the model. I just haven't had time to poke at this stuff recently. As of right now, most of the antenna are configured as destroyable untargetable subobjects, though I didn't make a table alteration to take this into account and so they don't do anything at the moment. My big goal was to have a working version in mv_models 3.6.6, and that's been accomplished. Beyond that, I'll get to it eventually but it isn't the highest thing on my priority list right now.
Oh, and since the Orion has no less than 28 such objects, I'm going to need the limit on subsystem total hp removed. I don't want to weaken anything else in order to have these extra things around.
