Plenty of us have done something similar to what you're suggesting, but it usually takes more like 20 weeks (not that I'm advising it for you).
And it usually involves a Dbol kickstart and a run of Winstrol or Var at the end to lean out.
Honestly, I've tried both and prefer to just run each cycle with a clean diet and keep it shorter rather than try a drastic bulk and cut like you're trying to do.
