I remember reading long ago that a capital counterpart of U+0138 LATIN SMALL LETTER KRA had been proposed, but was rejected because it could be represented as (I believe it was) the sequence <U+004B LATIN CAPITAL LETTER K, U+02BC MODIFIER LETTER APOSTROPHE>. Unfortunately, I can't find the details now, so I'm not sure if that's the right sequence, but it was something like that.
But the real point I'm getting at is: would it be productive to add a LATIN CAPITAL LETTER KRA named sequence for <004B, 02BC>? —Ben Scarborough
