I do like that one myself, but I'm thinking I'm going to hold off on developing that one for a refit/relaunch of the class that would happen around the 2290s or so. It feels too out of place in a ship from the era I'm going for. Right now she's vintage late 2260s/pre2270s TMP design. I definitely think I'll keep the ability to easily swap out components in the secondary hull for various missions with the refit so I'll model up that variant of it eventually.
The current dish itself rests right into the housing that has all the nuts and bolts. It's basically the same attachment system that the TOS Enterprise had minus the ability to rotate the dish, not that they ever moved the dish in TOS but the model had the ability.
