Looking for a couple of NPCs, BGOs and blocks in the SMB3 palette for a train/Western-themed level

[IcarusBen]

Sorry if this is a bit excessive, but I'm looking for a variety of graphics for a sort of western/train-themed level. In particular, I'm looking for:

-An SMB3-colored Birdo wearing a construction helmet (he's the mid-stage boss)

-A Boom-Boom wearing a train conductor's hat (he's the end-stage boss)

-An SMB3-colored background object that shows a star-powered reactor that powers the train, both with a visible star and without a visible star (since the star is supposed to come out of the reactor)

-SMB3-colored blocks for the exteriors of a). the front car of the train, b). train carriages, and c). the train kaboose, preferably with a comfortable large platform that Mario can stand on, and a sort of indent where I can place a pipe

Thanks for this, even if you can only fulfill one of these requests. Also, if any of you can recommend good music to use in a train-themed level, I'd be very appreciative.
