I am not clear on precisely what you are suggesting but my prior 
probability of StataCorp letting you doing anything 
of the kind here really is zero. 

Once you start overriding the inbuilt priorities of 
Stata the scope for all kinds of horrible bugs and gotchas 
increases dramatically. The problem is not what you 
(think) are doing; it is the hidden consequences. 
As Stata's commands can be nested many times, these
are normally very much hidden from you. 

That is not to say that users cannot be frustrated 
on occasion by Stata's choices and that many smart
users can see a better way of doing certain things. 
But the answer does not lie in messing with Stata's settings; 
it's in exploiting Stata's extensibilitiy. 

To put it personally, I have been using Stata almost
every work day for 16 years and have written several 
hundred Stata programs and I know not to want to mess with 
Stata in this way.
