I don't think the slider would be affected all that much since the reduction in diameter is at the rear wheel while the C/S sprocket went up in size, which should reduce slider wear.
It would be interesting though to see if there is any effect on handling in regards to the torque effect on the swingarm.

That custom sprocket looks so much nicer than either the stock or your first try at a smaller sprocket.

You may be right since the chain hits the slider in the front and you have at least a quarter inch clearance in the back on a stock set up
