At this current point the Crystal Tower raids (now being main story related) have to stay as they are. Back when the content was current you would see stories of wiping constantly in CT being current at the time. With the current IL sync it makes the content a breeze to go through but also will allow new players to experience the story without being gated into that early horror.

They nerfed the entry requirements as well (Remember when you had to wait for fates to spawn to even get into that raid series?), so this will continue to stay the same and I'd much rather have it.

Thankfully due to XIV being so customizable you can put up a PF listing for people who want to take on Crystal Tower synced to min il and run it like that. It would be a bigger effort then a coils run but seeing as how we have people here who have done 24 Man Healer parties for Orbonne and 24-man RDM parties for Lighthouse the interest to try out interesting things is out there.
