My requirement is a two-node network (point-to-point). I would like to establish a channel at 2407 MHz, for which I am licensed. (1) What router might accomodate this frequency? (2) How much monkeying about with source will this require?
to do this you need an ath9k or ath10k device, ath9k is better, but forget 2407 Mhz, you can use 2402 Mhz,
You may need the ARADEN project. They have altered it to access xh. Ch -1 and 0.

static const struct ieee80211_channel ath9k_2ghz_chantable = {
CHAN2G(2387, 38), /* Channel -4 /
CHAN2G(2392, 39), / Channel -3 /
CHAN2G(2397, 40), / Channel -2 /
CHAN2G(2402, 41), / Channel -1 /
CHAN2G(2412, 0), / Channel 1 /
CHAN2G(2417, 1), / Channel 2 /
CHAN2G(2422, 2), / Channel 3 */

You want to use narrow channels, your "licensed" falls within common wifi channel 1 2402–2422 , driver requirements already noted, you might need to scavenge good ath9k pcie card from ancient router or laptop
