in *gutiska-. Some of the earliest records of the Goths' ethnonym
have <gut->, so it doesn't rest on my inferences.

All right then:
*gut-a-, *gut-isk-
*got-a-, *gut-isk- (a-lowering)
*got-a-, *göt-isk- (umlaut)
*göt-a-, *göt-isk- (back-formation, cf. German <Däne>)
Get-a-, *get-isk- (unrounding)
As for the existence of -isk- in Thracian ethnonyms cf. Scordisci
(unfortunately for me without umlaut, so I'll claim dialect
differences).
