You have it a little in reverse here. The nomadic phase unfortunately is the one that sets up the place you want to be in and thus creates the situation for a woman to naturally fall into that. One of the better things to do, possibly ideal, would be a move from an EE country to a LatAm environment (there's a lot of flakiness and simping in LatAm due to it's indifference to an infidelity culture), but that gets complicated for many reasons, mostly visa and other such issues with the woman's home country and travel (unless you're a permanent resident in the new country and their laws aren't awful).
So is what you're postulating here along the lines of, hypothetically speaking, meeting your wife on your nomadic journey in EE, let's say Romania, and transporting her along with you into LA, say Argentina?
Therefore increasing odds of someone more compatible with you in EE while decreasing the odds of falling into adultery/fornication in LA due to temptation (this is why I put Thailand as "risky" for the same reasons. I cannot be there anymore because I cannot contain myself, and the culture is entirely alien/pagan), and also someone less likely to be compatible genetically and culturally.
I'm just trying to follow you. Essentially I believe you're describing a potential situation where BOTH you AND the wife are engaged in the nomadic venture together, to plan and build this life in the exploratory phase of searching for an ideal place to create your own 'little Eden' (doing this along with her would help make the travel purposeful rather than crumble into selfish musings).
Romania interestingly has the same Italian kind of flair that Argentina does. It wouldn't be hard for a Romanian wife to learn Spanish either, being that they are both Latin based languages. I'm sure there are even some Romanians in the ROCOR communities in Argentina.
The air of war has to be considered (and even if not directly attached to a place like Romania, the region itself gets effected economically), and Argentina in many aspects is a haven against WW3, while Romania most likely isn't, even with regards to lesser atrocities like an unfortunate invasion from Russia or what have you.
Of course there is the feasibility of traveling back and forth from Romania being unrealistic. It's a long journey with disruptive jet lag. Argentina is shorter but can be burdensome on the pocket, so I have looked into routes that don't fly in directly such as landing in Uruguay and taking the ferry over which would save money with frequent trips with the wife.
The visa situation seems much easier obviously also, for with Argentina we'd only need to be a resident for 2 years to gain citizenship (I imagine this process is the same for a Romanian wife), whereas Romanian citizenship is more complicated.
The exchange rate at least for now in Argentina is great for USD. And the new president, even though he's a ZOG puppet, is kind of like a Trump figure so at least he would hopefully get some things right that shield citizens from tyranny, even if he's only to appease them as some kind of controlled op stooge. Maybe that would mean things like no mandatory vax, no digital ID, etc. The universal healthcare is nice to have also, along with being able to buy and own property, businesses can be 100% foreign-owned, etc.
I think one key pitfall is that many women in the EE won't want to leave their families and their homeland, but it's important to mention here, many of those who have immigrated to Argentina have done exactly this. There is a shared comraderie there (I.e. Russians and Ukrainians fleeing war torn areas).
There are women who are widowed. Those who are orphans. There are the gypsies. I'm sure there are many souls in Romania that yearn for a new life but at the same time don't want to go to the Great Satan of USA, and would be comfortable leaving their old Soviet block as it's become a place of despair for them.
Is this kind of what you're getting at?
