Could be days weeks or months.

I think this it's generally a good idea to have larger UTXO's in cold storage as it's likely that fees will be high in the future. I wouldn't consolidate ALL of these UTXO's though.

(Q.) Wasabi Coinjoin Steps

PictureRoom

Hmm, okay. So from what I understand in what you're saying here, is to send each UTXO from my cold storage, to my wasabi hot wallet, but not all at one time. Stagger it out over a few days. 

Then, all of those sent UTXO's in the wasabi hot wallet will be mixed. After mixing, I will have multiple UTXO's in many different sizes. 

I would then send those coinjoined UTXO's from the wasabi hotwallet in larger UTXO sets back to cold storage
