As far as I know, its ok to highjack your own thread. I did it with Centurus once (he was trying to make an Excelsior variant) and it ended up with me being forced to eat some cookies with milk.
But to be ontopic (a bit more than everything else I've written): I would say keep going with this. Maybe make some sort of Steam Miranda. Or even better, the Steamrunner (with pipes and crystal balls)!

Make it a literal steamer!
