So rather than being "cross-class" abilities I guess it would be more semblance of an optional PvE skill set you could hunt for whatever lore reason. Like "Oh look! BLMs could heal after studying the CNJs'. We can do something similar with the dark powers of the void" or however you'd go about it.
Pretty much what I was getting at with the first alternative.

" Extend the number of cross-class skills Jobs can take and let the "skill book" acquired skills be unusable in raids. "

Currently we are limited to like 5 skill slots and we can barely fill them. Extend them to the full 10 - or however many; I never actually counted.

Skills from Skill Books can be or not be limited to specific Classes/Jobs. e.g. A "last stand"-like ability that heals you to full at the cost of 50% of your remain MP and TP can be made available to all Jobs. A dash attack should probably be limited to melee Jobs since casters will want to stay at range. ...

Or like was suggested earlier in the thread: give people the ability to aesthetically change how their skills appear.
That would be boring ... no gameplay at all. -_-
