Bypass coverFlow for Wall View?

[blattacker]

I will first preface this by saying I'm not sure if this is supported or even possible in Big Box.

With that out of the way, I'm trying to build a masonry-style layout for the Wall views in Big Box so that collections with games at different aspect ratios (as a very simple example, North American SNES game cases tending towards landscape and Japanese SNES/SFC games tending towards portrait) can still display nicely without any odd sizing issues. From what I can tell, this is not something that can be accomplished using coverFlow. The spacing between items seems to be an offset, rather than, for example, setting a specific pixel (or relative unit) margin between items. I've tried using other controls to display the games in the view to circumvent this, but as soon as I replace the coverFlow control with something else (for example, an ItemsControl), Big Box seems to lock up. It's not throwing an error, but it's not displaying any games or details, nor does it allow you to navigate or leave the view. I'm not sure if this is due to a missing binding on the replacement control, or if there's something else going on here. If anyone has any ideas or suggestions, or if you know for certain that what I'm trying to do is not possible, please let me know! Alternatively, if I'm missing something incredibly simple, please don't hesitate to call me out on it either!
