Need help on Stem extension denial

[eram17]

I have applied for stem opt extension , and it has been 180 days since the initial opt got expired and I have stopped employment now .  After a month from now , if the stem opt decision comes as denied , can I get some grace period to remain in US and do the following : 

1) apply for second masters and extend the i20  and remain in US.

2) convert from f1 to h4 and remain in US until h4 gets approved ?

 

please help me on this 

 

thanks in advance
