I also know that 'miniscule' has more than one definition but I don't need to be pedantic.
"Miniscule" has only one definition: a misspelling of "minuscule." You didn't understand that?
I think it's time to determine which chimes will be used, so a current test can be performed. What's the point of choosing transformers before the chimes?
You're totally correct.
The transformer comment was info as to what transformers might be available. If, for instance, only 20 VA transformers were available, then it might not be possible to design a wiring scheme where a transformer powers more than one chime.
Many transformers will handle two chimes (depending on the chime, of course),
Depending also on the wire length and gauge.
so if two are connected to each transformer, three will be needed for six chimes. The buttons, OTOH, may need to latch a relay, but that's not a big deal.
The relays will never latch, since latching means switching and staying in the switched state. Any relays used in this will be set up to close momentarily.
Actually, we're all blowing air until the original poster does some things. Respond to the questions about possible layout and wiring distance, for instance.
