The biggest question would be, what is under the dinette seats. In our currant MH, one is only storage with the carpeted floor, the other side has part of the fresh water tank coming up to fill half the space closest to the wall. By doing a work around, box or something similar over the water tank, the dinette could be replaced by a table and 2 or 3 chairs.
In our previous hybrid trailer, the fresh water tank was under one seat and the water heater, water pump were under the other seat, without losing most of the water system, you could not take out the dinette. However, that dinette table was on free standing legs, so it could easily be pushed to one side for easier entry/exit.
