You are able to ShotR every Snapping Bite with 1 or 2 in between, and healing aggro from Seal of Insight and Glyph of the Battle Healer will make sure bats run straight for you. You will have so much vengeance solo tanking that the bats will drop in no time with a little help. Just make sure the bats are actually being tanked before the DPS open up on them.
Be liberal with your cooldown usage, especially when both the bats and the boss are on you. Vengeance means your Sacred Shield will tick for a whole lot, which will really help smooth your damage intake. The main upside of solo tanking is that healers only have 1 tank to worry about, and don't have to split healing.
Also, a Judgment on Humming Crystals macro is very nice.
