Such a thing, I would like to mine CLO, but I guess you can't do that yet

of course you can,
https://callisto.network/ ->> scroll down to the Pool Support, you have 15 active pools and the
hashrate/diff is now very low so you can mine lot of CLOs at this point
There are bunches of pools for Callisto miners, but I don't recommend to mine Callisto at the moment because it is likely less profitable than other coins.
if are you selling your mined coins on a daily base you are right, but, I am talking to mine CLO & support this new project and hodl on a longer term
