Battery Efficient Custom Android ROM with least bloatware to be used for WiFi HotSpot

Hi... Devs and Geeks Around!

Is there a light-weight custom ROM for a worn-out phone whose only purpose is to act as a 4G LTE WiFi HotSpot or USB Tethering.?

In addition to this, it must be able to place calls, have a call log, phonebook and send/receive SMS.

An inbuilt Real-Time Internet Speed Meter in the notification bar/lock screen would be helpful.

And Nothing Else! (No Google Play Services dependant apps please!)

....which aims that it should be the most battery efficient custom ROM out there.

My 2 year old Worn Out Device Stats:

Manufacturing Brand: LYF (Reliance)
Model Number: LS-4505 (FLame)
Processor: Qualcomm MSM8909
