Do you think an active effort to adopt a Multi-Level Management Sales TEAM in Structure would bring value to the organization?

This  may be based on the classes of customers you deal with and the style of approach required to make all classes satisfied.  A Multi-level Management Team in Structure is a good option and may do well for the Overall development and growth. 

I think it depends on the number of your sales staff and their distribution (per geographical area, product, market segment and customer types)

But it is not sufficient to adopt specific team or competency. It is required to Adopt and Adapt.

I agree with Mr.VENKITARAMAN  answer
