Gateron space bars would probably be the most feasible, I agree.
They also have ISO Enter keys now - if not too much trouble, then I think it would be nice to have that too in the same order.
I am into 7u space bars and ISO enter keys in matching color, preferably in the usual black and beige ones.

I have bought some ISO enter aswell as their windowed on taobao, gotta say they match well the color of OG cherry.
And it seems they even have black spacebars now : http://world.taobao.com/item/520956720785.htm?fromSite=main&spm=a312a.7700824.w4004-10070819993.10.jETstq (http://world.taobao.com/item/520956720785.htm?fromSite=main&spm=a312a.7700824.w4004-10070819993.10.jETstq)
That would be may alternative to get my old beige into use with my current ISO layout. Thank you very much for the reference.
