I will go just directory by directory, as you have it after you unpack Enhancer archive:
Soo..
C: dir. Copy only files which you don't have. No overwriting ! There will be not many, but few.
Classes dir: all the _new_ classes only from Gadget dir. Also infowindow.class and images/shared.image. I.e. nothing which will overwrite anything. That to have ability to use not so many, but still, apps which use those classes.
DEVS dir: can be also installed almost all, except Datatypes dir, there better go "one file at time" copy, just to be sure you not overwrite old one.
As a note for both dirs, dont bother to install those "AK" datatypes related things : Warp/OS4 datatypes for all those graphics filetypes from Oliver are faster and better.
Documentations dir: fully can be installed of course.
Firmware dir : also fully can be installed (need it for radeon video hardware accleration and co).
Internet : can be too (just single file)
Kickstart : all can be installed.
L: all can be installed.
LIBS: install all, just one by one, to not overwrite of what you already have. I.e. no datatypes.library overwrite should be done, no z.library overwrite as they originals. And no .zip and no .codesets, as you probabaly may have latest/better version version. General rule - copy all what you not have, and if when copy you will have "replace?" then skip, of course. So only new libs and co.
Locale: if you not in locale stuff and Enlighs lang is ok, skip it all together.
Prefs: There need to be carefull. They have overwrote there some, like Sound.prefs (and they have few bugs in, which wasn't ever fixed, and i tired years ago to asking for). Datatype as well no need it. And also, just nothing which overwrite originals.
SDK : if not in programming stuff skip it (and basically it anyway badly structured and not mantained well).
System: Be sure not overwrite some bits too (for example Format can at first looks more fancy, but it have bugs which original on os4 didnt' have).
Utilities: All can be installed.
But be sure you do it all by hands. No auto install.
Then, you will have clean os4 with bits from Enhancer which not broke your system and you will have best of progarmmers involved in (like work from Hans on 2d/3d drivers, warp3dnova, work of Daniel on ogles2, work of Andy on Multiedit,Multiviewer and XDock, work of Trixie on some classes, and some old and a bit updated tools like AmiDVD, SFS2, Tunenet, etc).
Hope it helps
ps.

But is it worth to use components which overwrite AOS4.1 FE original files in C, Prefs, Comodities, Datatypes folders? I understand that some of them might have some improvements/fixes to FE original files, however if at some point FE update 3 is released, that will be even bigger confusion.
To be honest there almost none improvements over originals. Only replicas with bugs. Some was ok (like sound.prefs), if only it didn't have bugs (enhancer's one visually better).
But lately, they switch to their own classes, code of which done to have same code base for os3 and os4 , and , some bits just looks really dated in compare with os4 classes coming in original installs. I.e. some button to press and some titles of some replaced classes looks really dated.
In other words : install all what new, replace nothing, and that will be fine.
