Blast. I haven't considered that.

Welp, I think I'm still going to try to go directly to registers rather than using device specific libraries, just for the learning experience.

re: SPI: I'm imagining something like: integrating some other IC into the SPI mix which would have, say, five or six high pins, each connected to a separate SPI slave, then in my SPI communication routine I could feed the IC a command depending on which IC I wanted to talk to, and it would bring that particular slave low for communication. I'm just talking out my rear end though.

It's a lot more than you need, 16 IO pins, 2 interrupts, etc, but it'd allow you to do what you're looking to do.
