What are the biggest hip hop "what if's" of all time?

These are all recent, high-profile examples, but this post is inspired by the following unreleased albums:

Act II: Patents of Nobility (The Turn) — Jay Electronica (2012)
What if it released in 2012 as announced?

PUPPY — BROCKHAMPTON (2018)
What if Ameer never left and the hyped album dropped as planned?

YANDHI — Kanye West (2018)
What if Yandhi was Kanye's 9th studio album and Ye never shifted into Christian music?

Look At Us, We're In Love — Frank Ocean (2020)
What if Frank could fully execute his vision for this era, unhindered by the Covid pandemic?

What do you think are the biggest what if's in hip hop history?
