Question concerning the original KickStarter OpenRov kit

I’m new to the OpenRov Forums so please forgive me if I’ve posted in the wrong forum topic. I’ve recently purchased an original OpenRov kit from the initial KickStarter Campaign. I purchased the kit from an individual in Australia through E-Bay. The kit is supposed to be about 40% - 50% completed. As of 6/30/2020 I have not received the kit but it has made it to US Customs. My question is this, should I build the kit as the original or since it is still under construction to try and perform upgrades to the kit now rather than later. I’m thinking about subjects such as improved motors, propellers, batteries, and controllers. Any guidance will be very appreciated. Many Thanks
