design idea help

[Dimetime35c]

okay i need help designing a crane system for my space station. ive had an idea of using the cupola as the cab and having an arm mounted on top of it. but that doesnt really work cause i cant launch it like that. any ideas on how to either build something better or launch the idea i already have. also i had an idea of using docking ports on the cupola so i can use different types of arms. like the ISS arm and the Braun arm. any ideas would be nice. again either the way to launch my idea or a better idea

update i got the arm on my station. i used the cupola and just launched it off a rocket. only trouble is i cant move the cupola around using the arm without the whole station moving. any ideas on that?
