I've never seen any benefit to turning a roast. If you want to minimize the crust, use a roaster with a lid or a roasting bag, but the rule is always low even temperature and slow roasting for the best meat.
A crock pot is also a good way to slowly braise a tough roast.
Coming from a beef ranch, we'd put a roast in the oven at about 100-125F at 7 in the morning on Sunday, do our chores, go to church and come home at 1 to a well done, tender roast with no turning. It gets a good crust on it which you can amp up with a good dry rub if you feel so inclined, but there's no need for turning.
Just low, slow and in a container of some kind if you don't like a crust on it.
Now, in doing just a bit of Google due diligence I ran across this article that suggests that aging is more important with an inexpensive roast than the cooking environment. We hung our beef for 14 days before packaging, so this wasn't an issue for us.

If you have a big back yard and a tolerant spouse I've had very good results with the Polynesian pig-roast style of roasting.
Dig a big hole, line it with rocks, build a fire to burn down to coals, wrap the meat in several layers of tinfoil and place on top of the coals, bury it with more rocks on top and leave for 8 hours. Delicious, fall off the bone beef from the cheapest giant Costco cuts we could buy on a boy scout budget.
My mother taught me to insert bits of garlic into slits made into the flesh of the roast before searing and then cooking it, something like what's described here.
Some people like cloves in there as well, though I more prefer that with bbq pork. For lamb, it's garlic and green olives. So, accordingly, you should be able to get creative and experiment with injecting some other things so the roast will take on flavors you prefer.

What could go wrong? Probably not much. The same process that turns beef into corned beef turns pork into corned pork - and if you use another piece and compare recipes, you might recognize the process from curing ham. You might have to compare recipes a bit - curing times ranging from two to ten days depending on the author - and the actual cooking process could require a slightly different timing, but overall, nothing specific to the animal.
And like corned beef, corned pork is sold canned as luncheon meat. The iconic Spam being an (slightly infamous) example.
I even found one writer that claims pork was actually the more „Irish” version for Irish families (beef being more expensive and mostly exported), while using beef became the American-Irish tradition, resorting to the (Jewish) brisket when beef was actually cheaper and easier to get than pork.
