I would give 1% a try. Not sure how you feel about sugar but around .75% will balance the salt and make it taste more sweet savory than salt forward.
If that doesn’t work you can lower salt more, cure 1 can be lowered a smidge too. I don’t do any curing below 1% but I know John,
@noboundaries does and is successful and happy with his finished product. Maybe he will chime in. Also if you end up below 1% salt it may worth a try to use JC’s method of 10% water of meat weight. This way you dissolve the lower salt and potentially get more even coverage in the bag.
