If you grew 2 branches out into 2 opposite triangles and then wove them sideways until you had them completely around the base, and grew the next node above out on the 2 opposite triangles and a layer up, them wove those around sideways, and then the next node up, and so on, but kept wrapping the branches at each node around the pyramid, and let side branching from those branches fill it in, I think it would be pretty cool, then let one cola grow up the top like an antenna to signal the aliens.
Your surface area would be far greater than a regular scrog. Then when every triangle is covered trim all tops back so its an even pyramid of green and flip it to flower so all the flower tops don't stretch too far away from the pyramid.
