That sounds good!
Formally, Dalibor would need to resign as Project Lead. Then, a new
Project Lead can be nominated and voted upon by the Group Leads of the
sponsoring groups. In this case, the Porters Group is the sole sponsor,
so the Project Lead can elect a new Project Lead in a single stroke. :-)
And, conveniently, the Group Lead of the Porters Group is also Dalibor,
so he can do all of this in a single email. ;-)

If you intend to track jdk8u (which I recommend), then you should name
it after that.

Then it's just as well to request a mips-port/jdk repo while you're at
it, I think.

Unless there's a requirement that repo names must match the project
names, it sounds like mips64-port is more logical. Such matching seem to
be the general rule, but otoh I find repos that does not fit project
names either, so maybe it's a flexible rule.
Even if no mips32 port ever materializes, I think this is a good choice
of name. If your port is only supporting mips64 and you have no
intention of doing anything different, then it's better to be explicit.
That way everyone's expectations on the port is at the right level.
