oGCDs have a little more leeway, though that isn't saying much. You'd need abilities that interact with procs, or deal higher damage than the current oGCDs. The former could make sword use contribute to mana generation without breaking the hard rules the devs created for RDM sword skills (i.e, they are either regular weaponskills that hit like a soft breeze, or enchanted weaponskills that deal actual damage). One suggestion I've been thinking about is an oGCD sword skill (requires melee range because I'm a melee proponent) that consumes Verfire/Verstone Ready and generates the proc's respective mana (+9 Black Mana for consuming Verfire Ready, +9 White Mana for consuming Verstone Ready, +9 B/W Mana if you have both effects active) on a 15-20s cooldown. I also still think Engagement's damage needs to be buffed and separated from Displacement's cooldown.
To answer your question regarding Fleche and Contre, they're likely there because actual sword skills (that require swinging a sword) couldn't be in the skill list due to the job being put in the ranged caster DPS category when it was introduced. My own hypothesis is that it's also a callback to an MMD animation of a spell fencer fighting a monster (because the swords she conjured in the video were very similar to the swords we see in Fleche and Contre's animations). I thought it looked ridiculous, but some people liked it.
