Yes please keep me posted on this as well. Possibly looking for one to relocate to where the stock intake box sits. I have custom intake and using the Odyssey battery with PWJDM relocator. Now I just have a big empty space in the engine bay. A nice stainless box would be a nice touch.
ok update I just got back from my Dads shop in Ohio, we made two styles of battery trays, I think we are going with the aluminum diamondplate for the material its light weight ,rugged,and will look good with a good polish from time to time, or can be painted. Both trays will have 90 degree sides formed to secure battery from sliding
tray 1 for an Optima yellow top or a little bigger
tray 2 for the oem honda battery
both will fit the batteries nice and snug, I will post pics this week, im working on a strap mounted to the tray that will be a quick disconnect and will hold battery securely
