Can't figure out if you are serious or joking.
How are you planning to pick up the tongue? There will be considerable amount of weight on the tongue to deal with which would require some sort of wheeled dolly.
Then you have the issue of trailer bumpers being nothing more than 20 ga sheet metal, you would have to reinforce that considerably..
Perhaps consider a Motor Home instead of a trailer, then you can simply drive it into position..
You will end up wrecking a trailer attempting to push from behind..
Of course there will be a bunch of folks posting they do it all the time..
