Help - extension beyond my current understanding to script. :)

I want to create a 5E script that would extend the "Advanced Effects" script (the one that adds effects to items), and I have a few questions.

Desire: I'd like the script to parse the item effects (specifically starting with weapon effects) that are added to the items by the Advanced Effects extension so that attack and damage effects can be applied on a per weapon basis without needing to add them to the character sheet. This will facilitate things like dual weapon fighting without needing to remember to enable and disable effects on the character sheet.

Laziness is the mother of invention after all. :)

Questions:

1) Is this a good idea given the way attack and damage rolls are currently done?
2) I assume I'd need to hijack the managers for attack and damage, are there any "gotchas" or other things I should be concerned with...side effects, other modules, etc.

Thanks!
