There are 15 allowed characters for operator names presently (aside from + and -), could we define the rule that an operator name can contain any sequence of alphabetic+underscore+space? characters so long as the first and last symbol of the operator name is one of those 15 characters? Another appealing option would be the non-matching but complementary pair <...> (I'd consider removing these from the 15 choices in we go that route) SELECT 1 <add> 2; I would probably avoid requiring back-ticks given their usage as identifier quoting in other systems - probably remove it from the 15 choices if we go that route.
