Permanent residency via EoR

I'm a married American (California) tech worker in my 30s, fully remote, and make around around 200k annually. My company is already multinational, with a very small number of workers in European countries with digital nomad visas that suck less than Japan's. My wife has the same work conditions and pay, but her company does not have any multinational stuff going on at all.

I've been looking into how I could take a path to permanent residency while keeping my US salary. There's 0% chance my employer would be interested in establishing an entity in Japan just for me, so the best solution I've found was to urge them to inquire at an Employer of Record service such as Deel. I understand the middleman will want a lot of money, but I'm okay with absorbing the costs, as the COL in Japan is so much lower than where I live.

The rough idea would be to obtain permanent residency, then bring the wife over on a spouse visa (she is willing to quit her job if her employer is not interested in accommodating her).

Does this make sense? Does anyone here have experience with EoR services and would be able to tell me roughly how much I would expect to have to absorb to pay for it?
