I've pretty much decided to go ahead and build a T2FD "radiating dummy
load", hopefully for use from 2 to 24 MHz.

Hi Rick,

I've seen discussion about cutting the length of this air-cooled
resistor (what do you mean almost exclusively receive? Use a 1/4 watt
resistor then!). A halfwave design at 2 MHz is going to be 6
wavelengths long at 24 MHz. The resistor/BalUn may match well, but
the resulting lobes may not point where you expect them to.

Very small antennas (let's say halfwave for 20M) will receive 2 MHz
quite nicely (or as well as the resistor will allow); and point in the
direction (broadside) you expect for any of these frequencies.

If somebody appears on one of the frequencies I scan that I want to talk
to, if he's not S9 or better I'll likely switch over to a "real" antenna.

You don't seem very committed to any particular "general" solution; so
what is your real goal?
