I agree they should be a T20 witness, but you need to speak to the Hive Whales, or get Leo folks to power up A LOT MORE HIVE, something like 100-1000 times the amount they already have.
I doubt if there's more than 10 Leo regulars with more Hive powered up than me, and my stake does fuck all in governance terms so the fact that I already voted LEO as a witness means fuck all.
Sad but true.
Having said that I think the next HF is bringing in witness vote decay, that may help.
