Sorry Ade but it cannot be done.
We cannot take an eaw.exe like 1.2 or 1.26 or even 1.28E, and modify it.
What we have is a folder of source code files.

As you can see there are 543 items in it, most of which are needed.
We also have the software to read and modify those files, and then build a new eaw.exe from them.
For example Ralf has done some work on the bullet trajectories recently.
To do this he would open "bullet.c" and then modify the existing code, or add some new code.
Then he would compile a new exe.
