I used to think this was a good idea. Now I understand that consolidating UTXO'S is terrible for privacy.

If you think fees will come back to around where they are now in the next 5-10 years then I'd just leave them. If you don't you can swap them for lightning into your larger LN channel, then loop out larger UTXO'S. You could also swap for liquid or an ecash to get those smaller UTXO'S into better places for spending.
