No, it is not. I'm sure of this.

It can be made by hardware, because Z380 has a special feature, like an
interrupt when an unknown command is found... So these instructions can
be redirected to another single processor that only execute these instructions.
It would be a lot more interesting, because avoid changing programs.
(AFAIK, this thing can be done even on Z80, but the processor for R800
instructions must be BEFORE the Z80, and this will be a bit more complicated
to build).
but... it will be almost cosmetic, and will exist only for "strange" the strange
opcodes present on R800 and not on Z380. Besides, Z380 has a couple
of MULT instructions that are not present on R800.
And all "secret" Z80 opcodes are documented on Z380.

The MIDI is not necessary. The PCM is. BUT this can be easy copied.
I'm trying to convince Ademir Carchano to made one for my CIEL 2+ Turbo.

I think it's wise to copy the TurboR one, only for compatability. Something
better must be added. The PCM on TR is very primitive.

Who is interested on reading only this type of subject can use filters, present
on almost all good message hearder (at least for PC, once I don't know any
message reader for MSX).

I think it would be nice to make the suggestions and discussions here, and
the need for a Web page will be only to comunicate to everyone the
decisions (and not the suggestions or ideas). I think the need is to
achieve into an MSX 3.0 (or MSX 4.0 if it will be backward compatible with TR)
standard. With this on their hands, the hardware developers can easily
develop their own hardware, based on the specs. And the programmers
also will find easy to find the information on the Web Page.

Create a redirection on http://www.cjb.net/ . So people can acess it using something
like:
http://www.phoenix.cjb.net/
It's free.
