Not strictly part of the 1x question but I was excited

This appears to be beyond reasonable stretch limits. Your derailleur pulley is right up against the cassette and that will make for poor shifting. You need to lengthen the chain and drop the derailleur down with a Wolftooth link if you ride this way.
