I'm sure there exist eaiser methods, I for one could just drop a pre made "network" file into /etc/config/network and restart. But it was a fun challenge and I learned something. When the other options pop up; I'll learn more! Enjoy your journey. @RuralRoots I have the suggestion saved to learn along with jq curl cat Thank you.
#!/bin/sh
echo "Running at $(date)"
uci reorder network.@[13]=12
uci commit network
/etc/init.d/network restart
logger -t yourIFname ":$(date) connection established"
## Undo examples:
## uci reorder network.@[13]=12
## uci reorder network.@[12]=13
## uci reorder network.@[13]=11
## uci reorder network.@[11]=13
## uci reorder network.@[13]=10
## uci reorder network.@[10]=13
## uci reorder network.@[13]=9
## uci reorder network.@[9]=13

# MULTIPLE PEER(2) NETWORKS CAN BE ADDED TO LUCI AND SWAPPED BY .sh
# These networks are known by the notations below. Goal is to find peer(2).
# Plug in a number, or examine your "network" file ~ vi , nano, gui ~
# Count the unique "config" entries to find your first and last peer(2) entry
#
# (uci show network.@[]) #example will show first top entry /etc/config/network
# (uci show network.@[0]) #example will also show first top entry /etc/config/network
# (uci show network.@[1]) #example will show second entry /etc/config/network
# (uci show network.@[2]) #example will show third entry /etc/config/netork
# ....
# (uci show network.@[13] #example ~~ 13th entry /etc/config/network
# last peer=wg0 current tunnel us-nyc!

# Per OpenWrt - CFGID's are assigned to WireGuard Peers in order a~z.
# Shown below as cfg0(a)6912, cfg0(b)6912, etcetera
# Static entries insofar as peers do not move in order, unless commanded to. This sh's goal.
# The command: (uci reorder network.'cfg0a6912'=) will move that peer <NOTE:AVOID>
# to the very top of your /etc/config/network file and the CFGID's will change!
# The command: (uci reorder network.@[9]=) will move that peer <NOTE:AVOID>
# to the very top of your /etc/config/network file and the CFGID's will change!
# These CFGID can be found by either using a web browser's inspect tool
# upon the peer in the setup section of the Peer Tab in Luci, or
# invoking a save and then inspecting the "unsaved changes" section,
# or uci reorder network.@[#] where # represents number (see above [1]) of config line entry
# in your 'network' file, and then using (uci changes) to view the cfg0xxxxxx
# or using (uci show network.'cfgxxxxxx') if you happen to know xxxxxx
# Last entry will become path>wg0 tunnel. In this ex. cfg0e6912 is path.
# This example demonstrate five peers added via uci or Luci.

This README is dedicated to making a cli uci install of the Wireguard services and sswg script to enable one to swap endpoint easily and quickly. The front end work is lengthy, mostly reading; yet the outcome is well worth the time, especially since most of the work of configuration is 
You can install and run the script to obtain the keys within the 
Internet access.
