Hi mate welcome back i know you have still been about thanks for all the upvotes :) Yes i have had a lot of thoughts of something like this to. I have been thinking down the track of converting my new to me Toyota motorhome to electric drive. With more electric cars coming to Aus soon like the Hyundai Kona and ionic electric cars there will be lots more battery packs available from wreckers in a couple of years. That will make it cheaper to afford batteries etc.
