Bite the bullet and respec to Feral, I am using a feral druid for boosting and they really kick ass for boosting. I actually have a pally same gear as my feral druid and I prefer the druid, their ability to move and aoe at the same time makes for fast runs.
I doubt it would take much to gear the feral druid either, is the Moonkin 80? If so, run a few days random heroics and you will be decently geared to boost your toons.
Just my 2 cents
