I hope your plan of going down the route of 'penny wise pound foolish' doesn't come back to haunt you. There are countless reasons that can lead to a denial, you can go through past AOS Threads to find them - but I can tell you one of such upfront, early filing has been known to lead to a package rejection or denial, albeit erroneously in such cases.
The rule of thumb AFAIK is for one to always ensure they are maintaining and are in valid status as at the time of interview, no just the time of filing. Good luck with your plan though.
