Not sure about that wrap around thing.
I experimented with the modal panels yesterday and I think it would work, yes. I've been playing with the shoulder hold for so long it has become second nature to me.
The font scaling is a good idea too. It's a little tricky since I built the inventory around this exact size. One possibility is to scale the whole panel up to 4x instead of 3x. Another is just to let the text wrap onto two lines where it's a problem.
