Or, indeed, you could leave out the hyphens and do the same; the Prop224 Onion address is 59 characters, leaving a budget of 63-59==4 characters or 20 bits; we could put these at the end, in the space marked "@@@@":

Existing checksum in v3 addresses aside, what would prevent using a second DNS label for a longer checksum if you wanted a bigger budget?
The labels are limited to 63 octets, but the whole name can be up to 255 (including label length bytes).
