I actually thought about this a little bit more, and while I'm not interested in using Visas, someone else might be, so since she's the only one of your Party that starts off as a Jedi already, besides Kreia, I thought of this.
For Male Characters
You: Guardian - Sentinel - Consular
Her: Sentinel - Consular - Guardian
Now what this means is that if you start off as a Guardian, Visas will be a Sentinel like normal, however, if you start off as a Sentinel she'll be a Consular and so on and so forth. For Female Characters this order would simply be reversed so if you start as a Guardian Visas will be a Consular and so on and so forth.
Kreia, imo, shouldn't be messed with in this way since she's more or less the one training you and should be considered a rank above you and not subject to changing her class based on yours.
