Questions about Thomas faces

[DealAjani]

K, my question is, can the faces and eye mechanisms for the Bachmann engines be taken out and replaced with a realistic smokebox door?

Dear Deal,
They can, but you'll have to fabricate the doors. Also, keep in mind the fact that they are basically caricatures, and they don't have scale proportions.
Have fun!

so does that mean that I can't just buy realistic smokebox doors for them? If not, I can make them anyways
