Not exactly. The more souls you absorb, the more powerful you become, not just from the knoweledge, but also from increasing the size of your shard of Akatosh, as in the god Aka not the Alessian one. All Dragons are more or less aspects of Aka, Alduin being by far one of the largest pre-Alessian Akatosh. This however would not change the fact that the LDB has a mortal body. Tiber Septim also did not become a god by absorbing Dragon souls or having a powerful Dragon soul. That's a baseless piece of Imperial propaganda used to explain the Blades commiting genocide.
