Could you upstream your changes to cosmos/go-ethereum? We would be happy to integrate

[yihuang]

we need to probably create a base release/1.16 branch first? Then I can create a PR to that branch.

@yihuang I created https://github.com/cosmos/go-ethereum/tree/release/1.16 off of v1.16.2. Feel free to make a PR off of that :)
