First-time poster here. I actually created a Reddit account just for this after seeing all the great work you have done!

This may be a Herculean task, or it may be completely impossible, but we are trying to figure out whether we can add another hall bathroom to this floor plan.

The image does not show the rest of the upstairs because we already know we cannot change anything in those areas. I have only included the spaces that could potentially be reconfigured.

Our ideal layout would include:

* A hall bathroom with a shower
* A hall linen closet (I put where I think one can go!)
* Two closets in the primary bedroom
* A hall or bathroom laundry closet
* A bathtub and separate shower in the primary bathroom
* Retaining the guest bedroom as is because it is really small already

A few important notes:

1. We are willing to shrink the primary bedroom considerably. It is larger than we need. We could move the wall as far as the red line shown, which would leave us with a bedroom measuring approximately 16' x 13' 9" (we'd move the bed between the two windows at the top if we shrink the floor plan). Two closets in the primary bedroom are non-negotiable. My wife would not be okay with a layout that leaves us with only one closet.
2. We would ideally keep both the bathtub and shower in the primary bathroom, but we are willing to give up the bathtub. We'd like to keep two sinks.
3. The new hall bathroom only needs a shower, not a bathtub. It also does not need a window.
4. The upstairs laundry closet is nice to have, but not essential. We would be fine with an apartment-sized stackable washer and dryer. This could go in the bathrooms or the hall. If in the bathrooms, we'd want behind a door. Our main laundry is in the basement, so this would only be used for quick loads upstairs. 
5. We cannot build over any portion of the stairwell. It is very open but there is a landing below that would not have enough code clearance.

Our main priorities are the new hall bathroom, two closets in the primary bedroom, and two sinks in the primary bathroom. After that, we would love to have the hall linen closet, upstairs laundry, and both the bathtub and shower in the primary bathroom, but we understand that some compromises will probably be necessary.

We would really appreciate any ideas or insight. We realize this may not be possible, but we figured it was worth asking!
