Idea for a Plot (Two)

A method for finding intelligent life.
I hope no one else has come up with this, and if so, I hope I'm rich comes when the time comes I use this in a story.

A planet is reached by robots. These robots are controlled by a sect of humanity which has gone into deep technological acceptance. I expect this may be 2-5% of the population by 2080 or so, these will be the people who exist in both virtual worlds, but also the physical.

The body these people accept is the body of an entire, planet sized workhorse. This is the plan.
1) mine the planet with a PERMANENT system of mines.
2) construct probes capable of travel with some form of machine sentience to report on.
As these are launched the mines go deeper and eventually 100% of the planets matter is systematically reformed into full size civilization finders.

3) meanwhile on the planet construct and maintain massive sub atomic experiments using colliders much larger than what we have now. We could imagine it as a method of developing faster than light travel.

This means it could be likely the last of the planets finder probes as you might call them would be traveling possible to further into the center of the galaxy.

I suppose it would also not be a bad idea to engineer some physical form once this post human civilization finds others.
Human form might not be a terrible choice.

What if there are other forces in this galaxy.
