No idea how well it interacts with Evil, but Icicles has key-sequence completion.

You can see all keys available at the current time (including after one or more prefix keys). You can filter (narrow) the set of candidates any number of times, by matching against key names or command names. You can sort the candidates in a few ways. You can traverse the key-sequence hierarchy (e.g., go back up prefix keys). You can traverse menu-bar menus too.

As with any Icicles completion, you can initiate this on demand or automatically (e.g. after a delay).
