Larry Hogan would make an interesting VP candidate on Harris's ticket. He's a Republican, but was a two term governor in the blue state of Maryland. (Maryland has a two term limit on the governor, so he's now running for Senator.) To the extent that the candidate for VP pulls in votes, I think he'd do an awesome job.
The fact that you had to explain who Larry Hogan is and why he would make a good VP candidate to pull votes, is precisely why he isn't a good VP candidate to pull votes.
