reload Terminal preferences .plist after change - terminal

Question

I used plutil to edit the plist. then I placed in under /User/<myUsername>/Library/Preferences/com.apple.Terminal.plist. I want it to update the settings without reboot the application. How do I do this? using defaults read com.apple.Terminal doesn't seem to make the changes take effect. I added a terminal profile to the plist and want the changes to take effect.
I tried making an import profile with AppleScript but long story short it's not 100% possible. if you store window 1 so it's the same var in-between delays right after open it errors more times.
on run argv
set importScript to first item of argv
set flag to application "Terminal" is not running
tell application "Terminal"
open importScript
delay 1.0E-5
activate
if flag then close back window
do script "exit" in window 1
delay 0.5
close window 1
end tell
end run

there is no need for editing plists just a simple AppleScript. the limitations of this are you must have _oti_<yourProfileId> in your terminal profile default header and change the title when running your terminal profile to prevent accidental closures when installing the same profile of an already running app
import.applescript
on run argv
set importScript to first item of argv
set closeScript to second item of argv
set profileId to third item of argv
do shell script "open -a Terminal " & importScript
do shell script "osascript " & closeScript & " _oti_" & profileId
end run
closeMe.applescript
on run argv
set c to first item in argv
tell application "Terminal"
set wList to every window
repeat with app_window in wList
set wname to name of app_window
if wname contains c then
do script "exit" in app_window
delay 0.312
close app_window
end if
end repeat
end tell
end run
and then you can call the profile using this AppleScript
on run argv
set flag to application "Terminal" is not running
set scpt to first item in argv
set n to second item in argv
set p to third item in argv
tell application "Terminal"
set newTab to do script scpt
set badFlag to back window is equal to window 1
if p is not equal to "" then set current settings of newTab to settings set p
set custom title of newTab to n
activate
if flag and (not badFlag) then
do script "exit" in back window
delay 0.1
close back window
end if
end tell
end run
