Custom field select list populated with git repo names

Question

We want to add a custom field that lets users pick a git repository name from a list.  Our JIRA (5.2) is integrated with Crucible and we have Script Runner installed.
I have it in my head that a Scripted Field could build a list of options for the values by querying either Crucible or git directly.  I haven't a clue how to go about that.  Do any of you?
Thanks very much,
Mike

That's a nice plugin, Andrey, but I don't think it'll get me what I need in this case.
