Ethereum and Saved process (A gas fee question)

Hello Eth community,

I've been looking into depositing some rEth into Aave but before I go ahead and do it I would like to ask if I have understood the fees I can expect to pay reasonably well.

Due to fees I haven't used main chain very much for years.

Here's is my idea of how it would roughly look like:

3.31, withdraw cex

15.6, swap to reth

20.5 approve reth spend

20.5 deposit

20.5, approve borrow coin

20.5, eithdraw borrow coin

20.5, repay borrow coin

20.5 withdraw rEth

total: ~142 usd

How does this sound to you guys?
