Some limitations to that pretty sure. I paid my car fully in cash on my student visa and was able to get the car fully registered in my name. Carried over to my dtv no problem. If you have to do payments it's a more intensive process and they told me not possible when I asked about it before.
Just do a mini vacation. They want too many stuff such as a photo of you at home, bank verifications, multiple trips to immigration, etc. Just less of a headache to leave and come back. Work 6 months, take a break, and come back and grind again
