You can't really compare them to Lil Wayne, because they're different eras. Lil Wayne blew up in the internet era.
Pac would've been Latifah, Will Smith status. So he'd be well known for acting, but completely an after-thought for music.
Biggie is an unique case. For one, he was loved for his music but how would he transition once the inevitable "fall off happened"? By early 2000s, he's a legacy act. Even with the split from Puff, what happens next? For 1, Puff will either block it or still be heavily involved. And Puff's artists didn't last that long. Could he have transitioned like Nas, possibly, but also Nas took years of backlash and really just wanted to make music his way. In the long run, it paid off. Who else has that patience? Think about it like this, Kim has EVERYTHING lined up, and still became a caricature by mid 2000s. Snoop the same.
