Yes, you are right ...i do have sed to do replacement but did not share for the sake of making it look simple for others.
I don't know if I understood correctly and if i can work this out.
What i understood is
You asking me to keep the find inside the while IFS= read -r var loop ?
Is that correct ?

I'm not talking of improving the innermost loop here - although there is quite some potential.
Why don't you leave the looping to one single instance of e.g. awk?
Create a list of all file candidates (find can have several paths as starting points) and run awk, first reading all the search/replacement pairs, and then working those on all files presented.
Keeping the find inside the while IFS= read -r var loop helps cut down the time taken by more than half !!
Here is the latest code snippet
Can it be optimized further ?
