Can the Hull series mount the Endeavor modules?

I don't think so. I think the attach points are pretty different. Especially because the Endeavor modules are going to require you to be able to... they're all manned modules. You have to be able to walk in and get in them. I don't think they're interchangeable.

They're both MISC ships.

They're both MISC ships and similar styling. They are all manned modules. Hull Series are not designed to meet the power requirements of the modules. It's the difference between a station wagon and a supercarrier. That's a terrible analogy. I'm sorry.
