TBH the design has never really worked that well for Ironhide. Where you get a design like Prime or Brawl for example (the movie head designs were less than impressive mind you) which does work well as a homage at every level (even more to the point, non-movie toys like Bludgeon, Powerglide and Seaspray; Ironhide's design has been more a case of a Bayverse Transformer that turns into a ute and is called Ironhide.

I was open to seeing how it looked in a G1 colour scheme, but this has simply confirmed that the design was never really that good of a homage to begin with.
