can we have 2nd raise ability via item ?

No thanks .

If we're having to have classes mixed with jobs in our parties, something somewhere needs a fix.

I'll consider mixing classes with jobs to be training wheels for the transition at best. Never something expected to be done.

Actually, no. I can see some pretty valid reasons to still use a class even after jobs, and access to Raise as BLM is one of those reasons. In fact, access to more defense / healing abilities in general is one advantage of a class over every job that's not WHM and PLD, in case you want to play it safe for a certain battle.
