Are you saying your wheel inside width is about 32mm wide? Or do you have a wheel that has a 27x1¼ tire on it and mistakenly think that means anything for the question you ask?
Without knowing the inside width of your rim, preferably in millimeters, then we'd really be guessing. Sometimes that is on your wheel rim somewhere or maybe with the model number of your rim and some searching we'd know.

mmm no im saying the tires i want to throw on these old 27x 1 1/4” rims are slightly more narrow because they are 27x1” tires. The inside rim width is more like 17mm

I can't imagine any problem.
ASSUMING hooked rims, because you will have to run higher pressure to avoid pinch flats.
Harsher ride.

Sure. If they're steel rims without bead hooks, I would be wary of trying to achieve the maximum pressure that a 1" tire would have on its sidewall, but apart from that you should be fine.

The only way to know for sure is to put 'em on, and press 'em up until the bead blows off with a load explosion. Then remount with a new tube and use a little less pressure.

I would be worried of problems if the rim is wider than the tire when mounted, but that is unlikely. As long as the tires are at least as wide as the rims (preferably a bit wider) then you are good to go.
