Hi Luis,
we are not allowed to do so.  Donald Knuth allowed everybody to modify
or extend his program.  He even encouraged people to extend it.  But
he also said that no modified version should be called 'tex'.

pdftex is compatible with Knuth's tex, but because it's name is not
'tex', it can provide additional features (such as etex).

But what do you want to achieve?  The etex binary already supports
mltex and enctex *because* it's based on pdftex.
