Depending on how you grow, I would have to say the time lost while re-vegging an already matured flowering clone is made up for by giving you a really bushy (slightly mutated temporarily) plant that would do well under a scrog net right from the start.
Think of how much fimming\topping and throwing away plant matter it takes to get an even screen of green with an immature plant from clone or seed. The extra time you had to veg\train it is cut away and tossed into a pile anyway if you consider time as plant matter.
IMO "monster super cropped" clones are the way to go, especially if you like growing large 1-2 lb plants with scrog nets. I actually prefer to clone a few weeks into flower.
You might as well get a good head start, and air layer you some nice huge clones right away (I've cloned 3 ft tall & wide branches, with 1/2" + stalks this way). Your rooting success rate will drastically increase by "air layering", not to mention cut down on the time it takes to root. No need to take cuttings when you clone plants this way, as they stay attached to the mother until they are rooted.
Either way, the longer you wait while the plant is under a 12/12 photo period, the more chance your going to have a monster crop clone. That's a good thing IMO, as a bush is far more able to utilize indoor lighting then a tall lanky plant is.
Short answer: Yes
