Are the readings 下【した】 and 下【しも】 equally acceptable


Are the readings 下【した】 and 下【しも】 equally acceptable in the following sentence?

また、猫背【ねこぜ】になると、胸【むね】全体【ぜんたい】が重力【じゅうりょく】で下【した】に引【ひ】っ張【ぱ】られてしまいます

_Also, when you hunch over, your entire chest is pulled downward by gravity._

There are similar questions here; an answer to the second questions leads me
to guess the reading in the sentence above is 下【した】

When 下 is used on its own meaning below / under / down, etc., it is always
pronouned as した. It would never be read as しも in these cases.

When it is used in place names, or combined with other characters to form a
word/phrase, the pronunciation is often changed, e.g. 下【しも】ネタ, 下北沢【しもきたざわ】,
下手【へた】, 下車【げしゃ】, 下流【かりゅう】, etc.
