IMO both D and E are correct;

E does change the initial meaning (1) VERY, (2) use of WHILE gives the extra emphasis on the when both activities were done - ie at the same time.

Use of VERBING1 AND VERBING2 (as in D) takes time period from the clause they modifies and therefore D suggests that BOTH SHOWCASING AND INCORPORATING were done present together when MODELS WERE INTRODUCED (the original sentence does not wants to give extra emphasis on time period of both activities. Therefore I will pick D
