Hasbro E-11 can be modded to meet specialist requirements, but keep in mind, blasters are always optional. One of the keys is making sure you have the correct number of T-tracks with lower row open and ensuring you have the proper holes. So, to answer your question, you will have to modify the E-11 to meet the specialist blaster requirements, but your armor can be specialist without a blaster. I know, its a little funny.
