I've had a similar strategy in mind for about a year now.
The only diffrence is I'd use Syntropic rows.
Syntropic rows are densely planted productive plants along with fast growing support species. They require regular maintainance to keep the rows in growth (avoiding senescence). There's no reason you couldn't use nitrogen fixers in there but it's not all about the nitrogen. Exudates & plant growth hormones that are released after a reset (aggresive pruning simulating a wind storm) are the real heroes with syntropics.
