Referring to SpaceX as a steamroller is a metaphor[1].
"In full force" is, indeed, an idiom that generally means "in entirety", "completely"[2]
"Steamroller in full force" is neither a metaphor nor an idiom. It's a mashup of the two, and a phrase hitherto unuttered because it doesn't carry meaning.
Put simply, the set of things that can be "in full force" generally does not include steamrollers.
Please see Orwell's essay I linked to. "Fascist octopus has sung its swan song" is an example there that is a similar mix of metaphors.
There are many ways this can be fixed; steamrollers can gain momentum, for example.
As I said - it's not a principal point; I'm nitpicking. However, I believe clear communication is important - so here is an opportunity to improve.
