Arri FCP Workflow - LUT's & converting .ari sequences to .dpx

Hello

I am in a bit of an emergency situation on a Arri job - I have been editing with ProRes files that are from an Arri shoot (no LUT applied yet so totally flat) I have not only the transcoded ProRes files which I have been editing with, but I also have the .ari sequences which will need the LUT applied and also converted to dpx sequences for vfx pipeline. A few .cube and 1 .cdl file were included in a LUT folder but beyond that I am not familiar with how to apply the LUT to the ProRes footage I am editing in FCP, as well as applying it to the arri sequences which will also need to be converted to dpq. I have access to Color & Davinci Resolve on Mac - as well as AE of ocurse but I need to know what tools & workflow makes the most sense in that I am using FCP - would a GlueTools plugin be able to take the LUT and convert to dpq out of FCP?

Any help would be great and of course we would buy this immediately!
thank you
Andrew
