This is definitely going to cause problems. U+03BB *is* the Americanist
lambda, and is recognized as such by the Handbook of the IPA, as
well, even though lambda (and barred-lambda) are not official IPA
If you need to introduce an uppercase for it for Heiltsuk that is
*not* U+039B, that will introduce the same kind of confusion that
is already present in the standard for various overlapping
case-pairs involving Latin schwas and barred- or hooked-d's. And it will
introduce further confusion about whether the Greek or the Latin
lambda should be used in NW Indian orthographies.
You are also going to run smack into the current firestorm of panic
regarding visual spoofing security issues. Anything that looks
remotely like any letter already encoded is headed straight for
the blacklists, and will end up disallowed in at least some contexts
that the users might have expected it to be allowed.

Inventing new case pairs for characters that didn't have them before
is a dicey prospect at best. They will end up being implemented
badly (and late), I fear.

There is no such rule. That is an assertion by Michael of existing
practice in encoding.
It is unlikely that the UTC would ever assign default case mappings
across scripts, but that does not prevent someone from using
an orthographic rule of that sort. Not that I think it would be
a good idea, but neither Michael nor the UTC nor SC2 defines what
communities *can* do in devising orthographies.
