In theory, it could be possible. But it would really depend on the weather conditions, the age of your plant and the amount of time it takes to become sexually mature. All plants are different, sexually mature means mature enough to begin to reproduce or begin the flower phase, I have had plants begin to flower as early as month old, while others can take a little longer. What is your weather conditions like? If you are getting fair, warm weather without any frost issues, you could begin to start bringing your plant outside, but it will take some time due to a process called hardening off. That simply is slowly bringing out the plant a little longer each day, getting it used to the outdoors, if you did not do this, it would most likely go into shock and growth would stop.
So it would take some time for your plant before it would go into flower, a minimum of a couple weeks, during this time you could potentially begin to harden the plant off outdoors. But like I said, all plants are different, its hard to guess when it would re veg. If you could get the plant into flower before April outdoors, there's a good chance you could haul decent smokeable bud from the plant, you can harvest as early as 6-7 weeks flowering and still be a good smoke. But my advice, is its not worth it, Your yeild will be incredibly small, i guesstimate a quarter bag, almost making the grow not even worth it. In my experience re-vegged plants lose their vigorous growth and are much smaller plants creating a smaller yeild. Veg that seedling you have indoors for at least a couple months, and train the crap out of it, so it is a solid bush when it is time to bring outside. Making sure not to bring it outside to early due to risk of going into flower. You could really achieve a monster outdoor plant by vegging indoors this early, If you properly amend the soil in a giant hole and water every day with lots of love, there's no reason you could not pull a pound plant this fall. Hope that helps, happy growing
