Could you do this using the %> and %< prompt expansion escapes?

x=abcdefghijklmnopqrstuvwxyz0123456789
print -r -- ${(%):-%20>...>$x%>>%5<<$x%<<}

That still needs a conditional to determine (( $#x > 25 )).  Perhaps then:

setopt extendedglob
pat="(${(l:20::?:):-})?*(${(l:5::?:):-})"
print -r -- ${x/(#b)${~pat}/${match[1]}...${match[2]}}

I don't recall whether ${(*)...} to temporarily turn on extended
globbing is very common in the wild, yet.
