You could do it that way, but everytime you get a new EPICS release you
would have to remember to change it.

The scheme that is recommended to change items defined in module_types.h is :

1) Copy the file base/drv/old/module_types.c to your application area src
   directory.
   
2) Edit module_types.c to delete things you don't want to change and edit
   those that you do.
   
3) Add module_types.o into your xxxAppLib (Makefile.Vx) 

4) In the startup file, after the "ld < xxxAppLib", exceute the function
   module_types.  e.g.
          
          
cd appbin     (example is for 3.13.2)
ld < iocCore
ld < seq

ld < xxxAppLib

module_types
          
          
          
This will over-write the default values before the drivers begin their
initialization.
