SO your motivation is to spend more time in AF lounge at CDG. That lounge is nothing to write home about.
You have 2h15 connection that gives you time to spend an hour in the lounge. That's plenty. The next BKK flight is 2 hours later so that makes little difference.
But after such long flights (including arriving at LAX), I would rather shorten the trip than lengthen it.
Sure arriving at 7 in BKK is rush hour is not optimal. But you will get heavy traffic anyway.

In any case, it is extremely unlikely that AF will change your flights except for a hefty cost.
