So coinjoining the entire stack will cost roughly ~3.5% of that stack in fees.
Is it really worth it to coinjoin the whole stack?

Coinjoining with Wasabi only costs a 0.3% fee. Definitely worth it.
Why are Wasabi coinjoin fees so much lower than Sparrow coinjoin fees
The coordinator is more generous (there's no coordinator fee charged at all for inputs 0.01 BTC or lower in Wasabi).
Additionally, the block space efficiency is much greater using the WabiSabi protocol since you don't do a self spending tx0 transaction, and you don't pay for the coordinator's fee output either.
