Oh boy....it worked. Once again, my steps, which I do *not* recommend uninstalling system apps at all, were (for apps like Google system apps such as Keep, Play Store, etc):
1) Uninstalled Updates
2) Ensured that no duplicates or updates folders for the specific app-in-question is present in Data/App folder
3) Opened Titanium Backup & searched for app-in-question
4) Backed-up said app within TiBU (this should be the app version prior to updates installed)
5) Then Wiped Data of said app from within TiBU
6) Then Cleared Cache of said app from within TiBU
7) THEN UNINSTALLED said app within TiBU
8) Rebooted into TWRP
9) Flashed Blacked out app
10) Wiped Cache/Dalvik
11) Rebooted
12) Profit!
13) Detached app from "Market" from within TiBU as I did for, an example, my Play Store just now...
14) Smile & say Thank You in any meaningful way on here.
You can't skip one single step. Especially #14.
15) If your finances allow, donate - (I did).
