I don't have time to check this for you now, but I'm guessing that if there is a user exit that you can set to run every time that you open a file then you might be able to do something like that. This would take care of each file as and when you open it directly, but I think it would not do anything with the components of an assembly.
I have setup in the customer defaults the following switch, but it doesn't overide the cdf file for an opening file:
File/Utilities/Customer Defaults/
Gateway/Visualisation/Color Palette.
It works only for a new part
...and in the last section of the dialog labeled 'Options' you can 'open' (which is the same as changing or assigning) the color-palette (.cdf file) of your choice. Note that there is an icon labeled 'Use System Color Palette' which will automatically assign whatever .cdf file is current being used by the system for new part files, to your current Work Part (be sure to save it afterwards to have it stay in effect).
If you're going to be doing a lot of this 'updating' of legacy part files, it might be best to create a visualization template so as to at least make this a semi-automated process. If you have an existing user defined tab on your Resource Bar (if not add one) first open a part file in which all of your visualization settings are set the way you would like all part files to be like including any legacy files which you wish to 'update'. Now with this part open, go the that user defined Resource Bar tab and with your cursor over some 'white space' press MB3 and and select...
New Entry -> Visualization Template
...and when the dialog comes up, assign a name and hit OK. Now whenever you have a legacy drawing that you would like to 'update' to your current standard just open the file and go to this Resource Bar tab and 'drag' the Visualization Template you just created onto the part file and it will be fully updated to your standard. Now just save the part file and you're done.
