It is a great initiative and very generous of you. One thing I don't agree is when people want to bring top influencers with millions of followers. I tend to believe those are the most arrogant and hard to deal with.
In my opinion, it is more efficient to bring is lower to medium level influencers with 10K to 200K followers. They tend to be more social and interacting with their follower base. Also, it is easier to convince those to bring onboard.
So, instead of 10 top influencers, 100 lower to medium level influencers could make a bigger impact.
I don't know if I could stereotype them as such. I'm sure some are arrogant though.
Anyway, I entirely agree with you, bringing many mid-level influencers is the best way forward. However, I only have the time to deal with 1 reward, so this is the best I could come up with. It would be great if I could split the 600 Steem among a dozen, but it would not be possible for me alone to keep track of everything.
