I think I understand what you’re describing. Skuid can subscribe to events that your Lightning Components publish (see here). With that in mind, you can probably load the intended Skuid page, but wrap everything inside it in a Wrapper that’s not rendered on pageload. Then, your other Lightning Component can fire off an event that the Skuid page is subscribed to. And finally, you can use the action framework to listen for that event, and fire off an action that would render your Wrapper (and all the page’s contents within it).
Edit: if this option works for you, then it’ll have the added benefit of pre-loading a good portion of the Skuid page, so that when it’s rendered, it should happen pretty quickly.
