(And my try isn't even the first. And not the last. It seems searchable interfaces are en vogue.)
I imagine that idea could do much more than just searching which plugin to start/load, but also for executing actions, maybe for "speeking" to SketchUp. Of course this would be better implemented on system-level(see below) or like Android's Majel or Apple's Siri.

For now we are waiting for Trimble to fix/complete their API ( UI::Command.proc), this plugin is otherwise not possible without the risk of breaking your plugins.
The UI::Command is a nice abstraction of a feature, it should contain as much metadata of a function as possible (icon, keywords, description), and then it can be easily accessible via menus/toolbars/webdialogs/voice/screen readers/keyboard search...
