I had an odd thought of getting Steeljaw mostly for the speaker. Not for Blaster (I don't have the right one) but for Origins Jazz. I thought it would probably have a 5mm port on the back to fit in his 'flip hand' socket. Then I finally saw the turnaround, and was disappointed that it was a hollow shaped for Blaster's fist, so it probably won't work.
I think I may have worked out something similar for vehicle mode, though, using a part from the Centurion Drone pack (also where the Bee gun came from). Not so good in Robot Mode. I hope they eventually do some more accessory packs, even if you don't have the right bot as intended they're great for options. Not shown here, using one of the larger guns and the Ironhide drill for Origin Wheeljack's 'creative endeavors'.
