Will this make for uneven brake pad wear because of a smaller piston/bearing surface and possibly a different amount of force being placed on to the pad from the smaller piston? Thanks for the help.

Now worries mate.
When the brake caliper 'clamps' there is more force required on the leading edge and progressively less. On very high quality calipers it is not unusual to see three or four different piston sizes. The net effect is improved braking and more even pad wear.
