Agree with custom clothing, but why can't androids wear their armour all the time? Yes, that's their skin and skeleton. They can already change it with meseta. A re-paint, maybe. A bit like decorating a car.
I disagree about the FOcast, even though there is a Tech-enabling card in Ep3. Androids and magic don't mix, by definition. If they did, they'd make all other forces redundant.
... Tanlines?! Okay... I also agree with (most of) your customisable options ideas, BattleAngel. Beach clothing in the seaside area would mean unequipping all shields and armour. Would be funny for a while.
Lol! Trust you to mention bandages. You'll all want them all to be properly immunised, like your HUnewearls.

10 Meseta for Android traps is good value. Don't change that.
Those service areas would be okay. You'd need plenty of signposts. It'd be a good idea to have the extra service areas on holiday periods, like Easter.
And the areas you describe are so much more hazardous and difficult to play. A bit like a new Ultimate mode. Yes. Maybe there should be another mode in parallel with Ultimate mode with those new challenges. I say new mode! New area and monsters! I'm glad there's an Episode 4

.
What else? There could be an option to:
-Manoeuver the camera. Zoom in/out.
-Move sideways while facing forward, by moving and holding down "centre camera" button like in the game
The Legend of Zelda: Ocarina of Time.
-Be able to select which target to hit (useful for HUnters).
-Get monsters to chase you forevermore as soon as they spot you (and not reset as soon as you leave room), so you don't worry about that invisible barrier between rooms (someone mentioned this already).
-Close doors, like in game
Baldur's Gate. Only smart monsters would know how to open doors.
