"Could it work?" Depends on you and your training history.
First, reflect on your training, recall what has worked for you, then trust your instinct and make a plan. Once you've set your "direction" get into the details. For the plan above, since there is only one top set, I would damn well want to know which accessories work best for each day and how I am going to adjust volume for peaking/the meet (besides the drop in repetitions),
It is similar to Coan's style. I believe he said something to the effect that the 10 and 8 rep sets weeks out were used to build condition and also to measure what numbers he could put out and that he would use those weeks to help him "pick his numbers" and how to approach his goal (the guy talks a lot about picking the right numbers). That is something to keep in mind.
I perform like shit on once a week splits and prefer high moderate/high frequency with work mostly done on the comp lifts or very close variations. Building up volume and intensity slowly and then tapering off. So I wouldn't do it. My point is, don't try anything too new or that doesn't flow with your training right before a meet.
