Again I see your point, but I also see complications that you may not be aware of.
If there isn't a workaround, perhaps I can suggest for you to add a reset feature. We would have to press and hold a combination of buttons on our controller in order to be able to do it. For example: START++O
Yes, we could try that. But I think it would create much worsened compatibility, not only to the games but also to other utilities, as mentioned above.
If you have explored OpenPS2Loader (OPL), they have two features that you can go back to OPL menu or turn off your console by pressing and holding various buttons on the controller. So perhaps you can make something similar, but it would just reset the display resolution to 480i and then the game's own settings would kick in afterward.
