Sure, and as said, as soon as you try to specify journal options (and possibly others), this immediately fails. You can apply the options one at a time, and decide some aren't fatal, or you can actually have your later remount have code to drop specific options, requiring implementation knowledge of any filesystem to be used. Or you say people who specify journal options in fstab don't get to boot.
But if you blindly attempt to apply fstab options later in the remount, some options will break.
