Safety module on other chains / cross-chain

What do you think about a cross chain safety module or simply deployed on each chain to allow everyone to be able to protect Aave not only on ethereum but on polygon, avalanche, harmony, etc … and generate % for that but not only on ethereum mainnet ?

Or imagine a cross-chain safety module, where it is possible to deposit Aave against XstkAave and generate interest on the chain or another chain ?

Moreover a pool like the 80 aave/ 20 eth pool (balancer) on ethereum with possibility of stake (stkAbpt) on other chains would be interesting too.

Since there is a lot of liquidity and Aave tokens on different chains I think it could be interesting

I don’t know the technical difficulty nor the constraints but I want to open the debate
