Crank Triggers and Accessory Drives

[alkysbc]

I am looking to run a crank trigger on the front of a balancer, but would also like to retain some belt driven accessories. Any suggestions about how to re-align everything short of shimming it all away from the front of the block? Im fairly surprised that none of the parts makers have a shorter pully that would accomodate, as common as crank triggers are. Suggestions?
