Actually, I've just started doing this on purpose/by accident.
Put out a very Sativa girl too early, she went into flower, sported some excellent buds, But at 20° N. she re-vegged.
Meh, just let her do her thing. While the old buds were still good sized, she went back into flower. Hmmm, now I have plenty new bud sites and foxtails. When the new buds ripened to mostly cloudy, the old buds were mostly amber.

That gives me two kine side effects on a single plant.
I trim off fox tails for the wake-and-bake then the Close-to- the-bone amber as a nightcap.
Lemonade!
It was just another happy accident. :)
Aloha,
Weeze
