Fork Sushiswap

I would like to fork SushiSwap and create a Defi that can provide liquidity to the UniSwap Pool.
The image is Defi's Gysr, and Gysr can provide liquidity/Staking to different Dex/Defi such as SushiSwap and UniSwap, and Staking Gysr's own native token.

Expected rough flow
・Fork SushiSwap, change the UI and create a new Defi_A
・Connect UniSwap Pool to Defi_A so that Defi_A can provide liquidity to UniSwap Pool

main point
・Use SushiSwap's multi-chain swap
・Provision of liquidity to UniSwap Pool (mainly ETH chain)
・Staking your own native token (corresponds to SUSHI Staking in SushiSwap)

Reference site
SushiSwap: https://app.sushi.com/
UniSwap: https://info.uniswap.org/#/
Gysr: https://app.gysr.io/

I hope to be able to discuss the details later.
