What metal to plate with brass?

Brass. Use the real stuff.

Nearly any metal, steel, pot metal, aluminum can be plated. You specified "bright brass". You need to understand that for a bright finish, the base metal may require polishing first. Then cleaning, bright nickel plating, and a "flash" top coat plate of brass,or any other decorative metal. Now you have a reactive metal that will start tarnishing as soon as it comes out of the last rinse tank. It will require a clear finish on top of the plating. 30 years ago, I used lacquer. Now some low temp powder coating is available. Regular powder coating uses temps of around 350 F to fuse. This temp will discolor brass plate.
You also must consider how many sides are for appearance. Racking holes for the plater may be needed. Your simple part just got more complex. The same part done in antique brass, copper, nickel, is a bit easier to do, no polishing. The parts are immersed in a blackening solution after heavy brass plating ( no nickel) and then vibratory finished to get the desired "patina" look. Lay them out on a board, fire up the Binks #7 with lacquer, and call it a day.

You may be way ahead to just produce the parts from sheet stock, and polish and lacquer. 3/4 brass stock will not be inexpensive. Good luck!

tank bolts: there's what you got here there's bronze and ...

so i've got fluidmaster kits carefully labeled as containing solid brass bolts, but they don't divulge what material the nuts are. the nuts don't seem to be magnetic but unlike the bolts which have no coating the nuts are silve rso they might be chrome plated brass or i suppose they could be stainless. color me retentive for wanting to know.

but actually it brings up another question which is that I tend to not use the nuts anyway and substitute 5/16 stainless flange nuts so i don't need to mess around with the washers. i'm wondering if experience of anyone longer than my own with such a combination suggests this defeats the purpose of not having dissimilar metals even though both are closs on the galvanic chart they still show as posing a corrosion risk.

any pedantic plumbers out there who want to weigh in . . . thanks, brian
