Not really, I mean you could have Germania up to the Elbe (and Marcomannia) conquered in the 1st century, but then different confederations would merely form beyond the Elbe in much the same way. Trade and interactions with the empire would almost guarantee it.
But in any case, a successful Gothic settlement would look something like breaking up their independent tribal leadership and settling them as Roman subjects probably in Thrace and other areas of the Balkans that were depleted of men. There'd probably be requirements for military service, though under Roman commanders rather than as independent foederati under their own leaders. This is how Rome had settled all groups before, with the partial exception of the Franks whom Julian "settled" along the Rhine as a semi-independent entity in order to help with guarding the frontier (and it should be noted, it was an incredibly successful move, the Franks would notably fight the Germans that tried to cross in the winter of 406-407, losing narrowly).
The Goths would resist this, as they did OTL. Though with better management and more forces available on the scene, it would be much easier to prevent things from getting out of hand and containing it (and perhaps dividing the Gothic leadership). The best way to do that is not have this whole thing occur while Valens is tied up with most of Rome's field armies managing affairs in the east, and so is there in Constantinople at the time to deal with the situation directly.
