If the new rules pass, that's if and I don't see any reason why they won't, there will be no strategy to bye pass the 183 days.
If it passes and you're out of the country for more than 183 day (without good reason ie, business travel etc.) you will be classified as a non resident and subject to the proposed tax.
I cannot see what all this backward and forward snipping and aggravation is about.
If it's brought in, it's in and that's it, plus even now if the tax guys are aware that your living overseas, there is current provision to tax your earnings, but as pointed out - it's a gray area and many if not all are dodging it.
