In my personal opinion, a setup like the one above requires precise attention to detail and the will to maintain a very rigorous plan each month. Money needs to be moved from point A to B, then B to C, and so on, until all requirements are met. I do not think this is a good option for most people as it requires more effort than most are willing to put in. Case in point, if you really want the 6% you'll research all the requirements thoroughly and make sure you can meet them each month. Posting on a forum is not due diligence.
Not meaning to harp on you at all, but chasing yield is a dangerous endeavor and those fees will rack up heavy over time if one doesn't pay attention and understand the situation in its entirety.
