Some good points there (your more serious ones), but would never really happen as they'd change the game too much. I think some would help, though.
How do you feel about stop clocks and sin bins? Too Americanised? I like the idea of the former to stop time wasting, but wouldn't work from a TV schedule POV as games could go on for hours even if two 30 min halves with a stop clock.
Sins bins is too American for me and would be very jarring, but some like it.
As for 9 subs, I just think changing basically the whole team kinda makes a mockery of the game, but you could be right and football is definitely heading that way. Everything gets expanded. As I said to
@soul24rage, it wouldn't surprise me if we see 32-man international tournament squads in the next 20 years (far too many but that is the way it is going).
Some good insights there though, have seen some of your posts and always a good read.
Edit: agree on inheriting cards. It fucking pisses me off when some hatchet man makes foul after foul, finally gets a yellow, then the coach hooks him to prevent a likely red.
