First, you can use t-posts or even build racks like Dexter Day has done or you can stack up against a fence or whatever but cribbing the ends is simple and easy once you learn. It also can look decent. If you want to use t-posts (buy them at Tractor Supply) to use like zap does, that is okay too. I still like cribbing as it is so easy and no cost.
Now as for the wood stacks looking bad. Again, I'd guide you to zap and Dexter's stacks but there are many others on this forum that are really neat. For sure neater than mine. In the pictures below, the first picture shows what the ends can look like after being stacked for several years. I think that is the same stack as the 3rd and 4th picture.

This is what they can look like stacked without covering and stacked with covering.

This is from a bit further away. They may not be perfect but I doubt anyone would call them ugly and they would fit into suburbia as well as the country. Show the pictures to your wife and ask if it does look too much like "country."

As for the holzhausen stacking, many have debunked the old belief that it dries faster. As for taking less room, there is no way a circle would take less room than squares or rectangles. In addition, there is much more work involved with the holzhausen stacking. If one likes the way they look, that is fine but that would be the only benefit.
I also question the wisdom of cross stacking the entire wood pile. That would definitely take more room and would not look as good either. I also would doubt one would gain much in drying time stacking that way. In addition, we have never noticed any difference in the drying time of our middle row when we stack in 3 rows together. Shoot, we've stacked over 20 rows together and never had a problem drying the wood.
I would choose a different method of covering your stacks. Yes, they make gray tarps and even brown ones and they are stronger than the blue tarps. However, if you have a space between the stacks, you would have to put something there to keep the tarps from sagging. It would not take much water or snow to ruin a tarp if there was no support under it.
