No, it is not implementable, and yes, it uses escape sequences.
(Maybe not involving the escape character, but at least explicit
strings left-to-right mark etc.)

The version I sketched has the advantage that the kernel does not
need tables with character properties. The Unicode bidi algorithm
attaches a default direction to each character.
So, some complicated rendering machine can implement Unicode bidi
(with 61 level recursion), and feed the results to the console,
using my simple console escape sequences.
