Alternatively, if you aren't in a hurry, wait until the mempool empties and then consolidate at 1 sat/vbyte.
Could be waiting quite a long time for that to happen again... The mempool hasn't been close to empty for quite a while now

I've been wanting to consolidate some stuff... and it's just not feasible with the current network state
Even the traditionally "quiet" weekend periods have been busy. And you can't just fire off a 1 sat/vbyte transaction and hope for the best any more... with a flooded mempool, the current mempool min fee is like 2 sats/vbyte
