Simple screen with 2 image buttons. Focus rectangle?

Hi there, I need to make a pretty simple screen with 2 **different sized** image buttons (the images are dynamically loaded from URIs). I'm currently just using Button components and setting focusBitmapUri and focusFootprintBitmapUri. But I'm not happy with that because there is no focus rectangle like on the RowList and other more complex components.

Is there an easy way to accomplish this? This seems like an incredibly simple UI, I'm shocked that it seems to be so difficult.

I had thought about using a RowList with variableWidthItems but I need to change heights too!

Any help would be greatly appreciated!

Thanks,
