Kaddish - different Nuscho'os

Although it would certainly not be Nusach Ashkenaz, has there ever been found a single manuscript or printing from any nusach/עדה , prior to the printed Siddur of Rabbi Shlomo Zalman Hanau in 1725, that contains anything other than Yisgadal V'Yiskadash (with a פת"ח under each respective דל"ת)?

I'm aware that in regard to some of the Vilna Gaon's customs there is doubt or dispute as to how he conducted himself. For example, the issue of the word Zeicher vs. Zecher, in parshas Zochor, as Rabbi Hamburger Shlit"a pointed out in his recent lecture on the subject of imbalance in contemporary halachic observance.

Is there any dispute or question about the מעשה רב's statement in chapter 54 where he writes: נוסח הקדיש יתגדל ויתקדש שני דלתין בצירי, כדעת רש"י בלקוטי פרדס שהוא בלשון עברי or is this the uncontested custom of the Vilna Gaon?

Kaddish: "Yisborach, v'yistabach v'yispo-ar" "Yisboraych, v'yishtabach v'yispoayr"


Kaddish Tisqabal:

Is the phrase; "Tisqabayl tzl'ous-houn uvus-houn di chol bays Yisroel" or "Tisqabal tzl'ous-houn uvus-houn d' chol Yisroel"

Aseres Y'may Tshuvoh: "Ouseh Sholoum" Ouseh HaSholoum"


Kaddish Yosoum:

Are these changes made by 'Nusach Sfard' (Chassidim)?
