Here's my

I would think seriously about leaving the floor plan the way it is. I would hate to give up a bathroom for convience and also resale value someday.

Ohhh.... Inspector D, I think you might be right. Fascinating. More eager than every to see!

Removing the 3/4 bath is another question. We wouldn't have to even in the current scheme... just something we're kicking around. Not sure about the current obsession with so many bathrooms. I read somewhere that you should have one for every bedroom. Whaaaaaat?! Not only does it seem really rare that every single person needs the room all at the exact same time but, more importantly, who on earth wants to clean all those??? More than one - sure, I get that. But 3? or 4?! or 5?!?!

Definitely talk with an engineer. It does look like an addition & the wall is probably carrying some load.
That doesn't necessarily mean there's no way to do it but be prepared in case you are told no.
It really depends on how the addition was tied in to the original structure, your floor joist layout & where the load was transferred to downstairs.
