WW - It is not something we see as value. We sit at the dinette to prep meals, eat, plan, observe what is happening outside, sew, play cards, and dry the dishes. We like the layout.
My brother chose a couch that makes into a bed and uses a portable table. It's a different approach to how the RV is used. Folks who do not like the dinette need to change their 23fb layout, trade for a different coach, or yield to compromise. There are several mods that have been posted. Your sketch looks like it will be a very workable change.
Negatives - the space under the dinette seats is valuable. Low to the floor over the axle storage should not be compromised. We travel with items between the seats. - the inward orientation makes viewing through the windows a twisting action. - you may find the overhead cabinets to be a head knocker, maybe.
Positives - the inward orientation makes TV viewing more comfortable. - it will open up the aisle space if a table is not used. - the shelving at the door will be useful. - it's your idea. Hard to get better than that.
Make it your own. We want to see the WW smile down the road.
