I'm not sure what you mean.
Like Loyce, I don't understand what this means. Do you want to 'obfuscate change' by exchanging it for Monero and exchanging it back, instead of mixing it or sending to a Lightning channel? What is a 'multi exchange'?
Yep, this is what i mean make mutliple swaps to obfuscate the change vs. send to lightning.
sorry it was not really well described.
ps: i found this article really informative :

You can do that, but you'll have a few downsides.
(1) Exchange rates; may lose some amount of
BTC due to exchange rate fluctuations.
(2) Not trustless (unless the exchange uses atomic swaps); a submarine swap is trustless.
(3) On-chain links may be possible; LN is off-chain and you most likely receive the full balance through multiple different channels, making it much harder to track by amounts.
