I don't know how well geared is your Smn or if you play it at all now but asking for longer buffs duration is absurd. My Hastega alone lasts for 5:30 min (the duration can exceed 5 min, wiki is wrong on this).
It's also absurd saying Smn brewing is weak when we have Cataclysm...

Now in abyssea i hit for those about every 30-45 second and depending on my double attack + triple attack mods from atmas and sub job I lay waste to my SMN and thats just on punching I am not even factoring in my 2k+ ws's. I am sorry a well geared melee job or blm or sch can totally out DD a SMN in a heart beat. And if anything this idea would make a great way for SMN to nuke harder faster or be a great support.
Sorry but my Smn has never been the weak/useless DD you are describing while running a Parser. Does that's means my Kannagi Nin, Sam (who sadly can't spam Gekkos for 9k), War and Blm friends sucks even if they have the best gear available? I don't think so. IMO the main default of the job is it need much work and investissements than others to shine but it doesn't mean that it is an impossible task. Exemple : Ifrit's Favor can be potentially stronger than Fighter's Roll but it need a high amount of Smn skill and the AF3+2 Head...
