Sistering joist


I'm Putting in a curbless shower. I need to reduce 2-2x8 spruce fir wood joist by 1 inch for a length of 48".

The joist are 10 feet long.

I think the deflection is of concern but looking for advice if I should be concerned with other factors.

Based on bddd/12 calculations the current value is 1.5x7.25x7.25x7.25/12=46.63.

If I sister .75" osb the value will be 2.25x6.25x6.25x6.25/12=45.77.

Any advice on deflection, strength or supporting load is appreciated
