Additional changes for a pair of Maggie 2.7 qrs? I'm about to pull the covers off to fix some delaminated wire

This is my first and hopefully last attempt at fixing my new speakers delamination and wire starting to come off( i bought them broken about a month ago) is there any other quick mods like capacitor upgrades or anything that can be done while they are apart that dont cost a fortune? I thought since im pulling them apart anyway now would be the time to do them-any mods that you know that work universally or anything along those lines would be appreciated.
