Hello!

Nope. IPv6 host routing is based on assumption of link-locality
of the next hop. Probably, you want to read some rfcs or to look into code.

Impossible, as I said.

  one sentence, written by me has grown to some huge tumor eating
  original one completely. :-) ]

Sigh, there no specifications about tricks used by Linux routing tables,
*users* are unlikely to want to use this feature at all, as Mika noticed.
And when they want, they want to right:

    ip route add 3ffe::.... via 193.233.7.65

rather than crap sort of

    ip route add 3ffe::.... via 2002:<something in latin>

I do not understand, what the hell is going on with you.
I am already sorry that started this. :-)
