As stated, it's lifted straight off my USS Horizon model, but manages to fit. But yes, something Excelsior like might work.I'd go for something like the one on the Excelsior instead of the Idea A that looks like a copy from the TMP Enterprise. Or stick with Idea B.
The "Neck" is a work in progress at the moment and is not done (she won't be bare).Tricky....
I love the look of A but the somewhat bare neck is a bit meh looking. You could do both, and make the drive-assembly from B into a workbee bay.
Thank you for the feedback. Will have a think about what to do.
