Somewhere several pages back is a thread on desert-style boots, akin in looks but not color to the 600s you got from Belleville, on closeout at lapolicegear.com. I looked a bit and didn't see it but it's there somewhere if you want to check it. In the meantime here's a link to the company page:
http://www.lapolicegear.com/wellco-3-layer-hot-weather-combat-boot.htmlSeveral of us bought the boots and I don't think any who did were disappointed. They're factory seconds, some were missing insoles, but the ones I bought for my wife were only defective in having a scuff mark on one heel. I recall at least one here, Viking, who placed an order and was told the size was not available, but he wanted size thirteens. There may be something in the size your wife wants. The mens' 9.5 quad-E she wants translates to about a 7.5XW in military sizes. There's no way to check availability before ordering AFAIK. You'll have to place an order and see if they send a "Sorry, Size Not Available" e-mail. That's how Viking found out about the ones he wanted.
Checking the link just now and found that they've gone up $11, from the $18.99 I paid to $29.99. Still a deal on boots that are regularly $110, according to the site.
As for dyeing, I've never dyed suede, neither for myself nor when I worked in a shoe shop, but I don't think it'd be a big deal. Check for a shoe shop or wedding store that dyes shoes near to you and ask them about it.
