I relish these sorts of problems. If you have a digital caliper to take some measurements and could sketch it up roughly, I can draw it up in CAD. Photos would help determine how complicated the machining job would be. I wonder if a 3D printed one might work? A pulley couldn't be too challenging depending on how it is fixed to the spindle. If by grubscrews then that would require a metal boss or flange as the plastic would not likely be be strong enough for grubscrew threads to withstand the torque. However if it's just clamped with a large axial nut and washer on the spindle it could be ok. Of course if you can trade for the right ones, that would be best of all :) Steve.
