Hi jbeezy from Lido DAO.
Of course I have bias but agree with making the SM more productive and having less direct risk being exposed to AAVE risk. I think adding an LST such as wstETH is a great idea. It could help the pools and assets be more productive in the underlying AMMs / Safety Module compared to standard WETH/ETH.
I would be happy to discuss additional considerations such as wstETH/bb-a-WETH support. This could have second order effects by increasing TVL on Aave markets both through direct deposits from Bal as well as the folded leverage loops that are popular with the kids.
GHO adoption will be a risk initially but I think Lido can help with bootstrapping efforts replacing as @Llamaxyz mentioned WETH, with a more productive asset. Which of course is not without its own risk.
We are already deeply integrated in the Curve ecosystem as well so would be happy to explore and facilitate new pools and the reWARDS committee could probably assist in the bootstrapping efforts. Lots to discuss here.
