Possible ?
Practically: No, not as such, unless you recompile 'Caja'.
There is no config where this can be changed. Most of it is hardcoded in 'Caja'.
If you are comfortable with hacking the sourcecode it could be done.
The MATE site is here
The sourcecode of 'Caja' is here
Bugreporting regarding the sourcecode is done here
I can't assist you with recompilation but I guess that you will find out how to do it. 
(or pay someone to do it for you)
