Class-specific lockers?

Here's a new idea (as far as I know)... One buyable locker slot for each class. 2k gold each? 2500 gold?
There are 19 classes, and extra slots cost 10k and then 40k for the main building... Seeing as it's already valued like this and this is like paying for one extra in installments with an added perk, I could see them costing 5-10k, but I wouldn't be that happy about it. 2k-2.5k seems a bit nicer, and less likely to encourage using the same class over and over again overall.
