Rear Ramp/Door Question

Any chance you think this might work. Cargo Trailer purchase with rear ramp and have a RV Door installed in it. I really would like a rear entry door instead of side door. However for marketing purposes down the road without a ramp door or barn doors would severely limit the market. I probably way out in left field on the thought process however i like the thought process this forum has. though with a door cut out of the ramp it would make the ramp almost useless, maybe I already answered my question. Thanks
