Barebones control of Leaf PDM for offboard charging?

[Zieg]

I'm not sure how good an idea this is, but I've got a Leaf gen2 PDM with the 6.6kW charger and I'm wondering what it would take to use it as an offboard charger. I'm thinking I could mount it to a frame, plumb a coolant loop and maybe use the dc/dc to power a coolant pump and whatever else is needed.

I'd probably just unplug the smaller OBC and plug in the Leaf PDM for offboard charging, as well as a second LV plug that could signal a BMS error to whatever is controlling the PDM via a low-side output. Car would be turned on manually.

I know the Zombieverter can control the Leaf PDM, but can it do so without a current shunt? I'm hoping to do this by cobbling together parts I already have, but I could see myself using a Zombie as my VCU in the future so I don't mind buying that.

Any suggestions appreciated, including pointing out any and all reasons this may be a bad idea!

It would be pretty cool if you could figure out a way to make it work like a DC charger.
