Can it be done?

With regards to Leaf towing a lot will depend on where you are based... UK/EU law differs greatly from other jurisdictions for example.

With regards to reusing Leaf components then sure that's possible... here's a great thread to start;

User skooler would also be a useful resource if you're in the UK.

I am trying to keep this simple, and from my very limited experience, I would like to get a suitable motor and controller to mate with the Leaf cells in whatever voltage combination.

Take a look at Damien's (user jackbauer) website which has lots EV projects using various battery cells (including Leaf) and motors. Damien has undertaken both direct drive and transmission based solutions;

You might also take a look at the evwest conversion kits;

I also hear good things about the EV4U 3 day courses which would answer many of your questions;

If you're in the UK I'd be happy to show you around my EV workshop if you're quick (we're in the process of moving it to the US).
