Dual Boxing 2 healer in raid question

[Ezekiell]

I'm new to dual boxing but I've read pretty much all the stickies. Since I'm new to this, I was wondering if dual boxing 2 resto druid in a raid setting would be "possible"? In other words, I would play my main resto druid while my 2nd resto druid would follow me and cast the same spells on the same targets.
It would be in Fireland :-)

By the way, I know it wouldn't be possible or viable for every fight. But Baleroc, Shannox, Beth, (maybe rhyolith), alys (if follow is good enough for tornados, and picking feathers hmm), would be possible I think
