safe to strip a M8 sprint of HTC n Sprint apps?

I have a rooted & boot unlocked sprint version of an HTC One M8. Twrp recovery
I have Titanium Pro, SU pro, & also root explorer.
I have Blinkfeed, dot view,kids mode frozen ready to dump. I don't know how large (MBs) the are and its non issue, I want that all gone.
I have played with freezing a lot of Sprint & Google apps but then my gps reports me out of the country I keep getting wifi calling has been turned off notice n I have to go back in the unfreeze reboot n then do the code call in for sprint. Wifi calling is a must for me!)
I wanna s off & completely strip it down to kk4.4 & whats essentially needed so bad,
I would be so 4 ever grateful if someone had a list i could just maunally go in & start cuttig off fat.

Thanks

I know I know should of bought a GPE
