Commercial Relationship Manager to Fixed Income Research

I am interviewing for the MBA Commercial Relationship Manager program with Wells. I ultimately want to move to Fixed Income Research though. Since FI Research roles are few are far between I thought a CRM role would be a good place to get credit training and experience until a FI Research role opens. Does this sound like a good plan to those of you familiar with FI Research if I cannot immediately get a FI Research role? Also, does anyone have an idea of salary/bonus for each of these roles at a place like Wells, say years 1-5?

I appreciate the help!
