Looks tasty. I just did something similar. First I made a shoulder using a spice rub that i came up with to mimic tacos al pastor (plus a pineapple juice spritzer).
The next day, i took some left over pulled pork and reheated it on the Weber GBS wok over some left over charcoal.
I'd call that a "wrap" over a burrito, though. IMHO, you'd need to serve it in an open face soft corn tortilla to call it a taco. Crunchy tacos and burritos don't really exist south of the border. Those are north of the border items. Call it delicious, though. Because I still have some more and now that i have seen your picture, i want to go reheat some more pulled pork al pastor.
