Answered: Can you de-score yourself?

Apparently you are not allowed to de-score your opponent by removing a cube from a post. But suppose you or your alliance had placed a cube on a post but you decided you could get a couple more points by removing your own colored cube from a post and placing said cube on your constructed skyrise. Would that be legal?

I’m asking in case a successful skyrise builder runs out of cubes on the field but has some cubes scored on posts.

<SG6> specifies that you may not remove ANY Cubes that are Scored on a Post, with the exception of the listed clauses. Thus, you may not descore your own or your opponent’s Cubes. <SG6> is quoted below for your reference.
