I would like to do that but the problem I face is that there is no
suitable specification for the original Curve25519. Ed25519 is well
defined and the printed and online paper should be sufficient as a
However an I-D for Curve25519  has recently been published. Thus it
may soon be possible to describe how to use it in OpenPGP. In
particular on how to use only the X coordinate.

No, that is for Ed25519.

For the Montgomery curve Peter Gutman assigned 188.8.131.52.4.1.3029.1.5.1
arlier this year.
