Help on making the TMNT 2012 main cast in Lego minifigures

Hello been making custom Lego mini figures for the 2012 TMNT series I have currently made Stockman Fly, Casey Jones and Rahzar and nearly finished Professor Rockwell and Rocksteady but have been struggling to find a good torso and legs for 2012 Bebop as well as a good torso for the season 4 and 5 outfit of April and a good head for Slash as I’m planning on making him brick built but want to use a minifigure head for him and I’ve not started to look for parts for Mondo Gecko yet but if anyone has any suggestions for him that would be greatly appreciated.
