I doubt it, or at least not this type of string; I understand that Schon insisted that all members of the band could at least play a guitar if it wasn’t their primary instrument (Perry himself is a bass player). However, a significant number of Journey’s songs are written in D and A. G would be more convenient on a viola, but it’s only a whole step up and tuning the thing a step up for those songs is at least a vague possibility. They don’t seem to have gravitated to C very often, unlike bands that are led by pianists, but they stick to the less remote keys very often nevertheless. And from what I can seem many of those keys are very string-friendly or else easily managed by tuning up or down a mere whole step at most. Nice!
A goodly number of their songs also have the feel of the 8-in-the-bottom type of time signature so often favored by singers. Singers love triplets.
