If the variables were appropriate/inappropriate for an mlogit/ regression/ ologit analysis I imagine the same would be true for gologit. In any event why not just try it and see if it works and if the results make sense?

Having said that, multicollinearity is not inherently fatal; you might have problems with a small data set and no problems at all if you have 100,000 cases.

Conversely, if you have a bunch of items that all measure the same concept, you may be able to create a single scale out of them that solves your problems.
