As an experienced Architect who is now a BIM Manager, I can only recommend patience. Things change rapidly in our business, and you can always make changes down the line. Don't be afraid of getting stuck in a role until death. BIM Management may be a great place to start, as long as there is a quid-pro-quo understanding that:
A) You wish to become a Registered Architect, and they will have to put you on tasks that will provide the required experience, and give you the partial time to accomplish them. This includes detailing, consultant coordination, design, specifications, and construction administration.
B) In exchange, you will utilize your experience working on projects and seeing first-hand the deficiencies of their workflows, in order to better innovate new technical solutions. They need to realize that a BIM Manager with no clear concept of an Architect's process is not very effective.
If you are not gaining the project experience you deserve, you need to be prepared to leave. This is where working for a smaller firm is of some benefit, as they typically need everyone to do everything, whereas larger firms tend to want people to specialize. Pigeon-holing can hurt you in your early career, but it's your responsibility to police your own path. Though this required splitting your time judiciously, I believe it's the only way to be a well-rounded, effective Design Technology Manager.
