Seeing I don't want to redesign my carriage, why not just use what works. Use the j-head on a body that can mount the chimera. I made it adjustable jut to clear other obstacles around the hotend, and to give clearance for other add-0ns such as fans, LED's, whatever. Of course you will need screws that are 10mm longer, also I would recommend stacking a spacer behind the Chimera so you get air flowing around the entire sink. This is still a work in progress seeing I just received my Chimera the other day :D
