Exclamation is it possible to modify text in settings/about phone?

I was wondering if it was possible to change, add, remove and replace the text shown in about phone settings?

Here's an example, My phone status in settings shows 'Modified', is it possible to change it to, let's say, 'Rooted' or 'Normal'.

I know Xposed Installer has a module to change the phone status from 'Modified' to 'Normal', but the option is not customisable, and there's plenty more settings text that could be changed.

If so, is it then possible to add text to the 'about phone' setting, like:
ROM: Cyagenmod 10.4.2 or whatever. (I'm not using a custom ROM at the moment, but hoping to in the near future).

Or even:
CPU Max Frequency: 1.4 GHz

That would look pretty cool on my settings, it broadens the amount of information displayed on 'about phone'.
