I currently have three pairs of speakers, and intend to add a fourth
as soon as this is all squared away (the wiring for the fourth is
already in place, I just need to connect them to speakers). The
existing three pairs of speakers are the in-ceiling speakers I've been
talking about. The fourth pair of speakers will be traditional
full-range speakers. That's one reason why I want to send the
full-range signal to the power amp (and in turn the speaker selector).

I think you might be confusing the AVR with the speaker selector; they
are two different devices. The speaker selector is a passive device
(it doesn't require external power). It simply allows an amplified,
speaker-level signal to be multiplexed. Without such a device, I
would indeed need to have a 1:1 power amp to speaker pair ratio.

Here's a concrete example of a speaker selector, Monoprice product 8229:
