I would suggest from experience that 19's are too big on a daily driver.
a 215/35R19 is a very low profile tyre and there is a high probability of wheel damage on shitty roads.
I would go for 18x7.5 or 8 with 215/45R18 or 225/40 R18
From the reading I have done 18x8 +45 with 225/40R18 tyres and a 2 inch drop will touch the guard from time to time.
in saying that if it is something you want to do then go for it, just don't expect it to be all positive.
