All your reduction will be from the disc side - a reduction of 5mm.
The drive side has to remain as-is to preserve the 8/9/10 speed compatibility.
This as FB already mentioned is going to throw off the disc positioning in reference to the caliper - if the caliper doesn't have enough adjustment space you'll be stuck in a tight spot.
Test first, check to see if your frame can already accommodate 135mm OR find a native 130mm disc rear hub.
