Wow - this is an impressive idea! And YES - I would absolutely love to have this! 
As a (both) teacher and social scientist, a huge part of my work is about showing up connections - and especially connections that are surprising and unexpected, means: everything is somehow connected to everything - but only if we succeed to leave behind the connections we know from our daily discourse and routines we will finally be able to really open our minds to the world surrounding us!
What would be really, really mindblowing: if we could tell the plugin to either follow the route by direct links or by tags! I have lots of atomic notes that are not necessarily connected by links, but by tags (I use tags for topics). A couple of months ago, I have described my working with tags (and the additional benefit of it) in this post - which somehow also shows the use case of your potential plugin for me!
So, great plugin idea anyway. If that would be feasible, some ideas/propositions for possible configuration options of the plugin:
- as already mentioned: option to chose between searching for connections via links or tags;
- another option to chose: “find direct/shortest way” or “find random way” - this would open up a couple of possibilities to find really surprising and unexpected connections!
- option to chose between: “copy note titles to clipboard” and “copy notes to clipboard”
Just some ideas and propositions…
How do you manage, btw, to still create new notes if you are writing plugins all day? 
Edit: just to clarify what I mean by “connection via tags” - doesn’t of course mean connection between notes that share the same tag, but let’s say, for example, I have the following 4 notes with the respective tags:
- Note 1 has the tags #tag1 and #tag2;
- Note 2 has the tags #tag2 and #tag3;
- Note 3 has the tags #tag3 and #tag4;
- Note 4 has the tags #tag4 and #tag5.
Thus, there isn’t any obvious connection between Note 1 and Note 4 (they don’t share a common topic and most probably there is also no direct link between them); but there is a route from one to the other - you normally wouldn’t see this route, but it nonetheless exists! And it is actually these routes life is made of! And discovering such routes makes you understand the world a bit better!
