Can UTXO be mixed by opening a lightning channel?

Hi,

no, if you fund a channel with a given utxo, it will be spent at the channel close. Thus it will be like sending a transaction to an address you control (minus the amount sent to the fundee).

Sure. The simplest would be if you had a lightning node with pre-existing inbound capacity. Then spin up a disposable node, use it spend the utxo into a channel with a 3rd party (make sure not to open a channel with yourself, or it defeats the whole purpose). Use lightning to send everything to your node with inbound capacity. Now close the channel. And destroy the temporary node.

It's not exactly perfect, but it should more or less do the trick.
