tub drain and overflow and ptrap question

[iananderson]

Hey guys trying to finish this plumbing project on the last leg now. I have a problem. The overflow sits on top of 2 joists and I had to put a sani t on its back with a sweep 90 down to the ptrap.
Now before I glue it together I wanted some extra eyes to see if my plan is acceptable. I have a pic Thanks in advance for any help

For ease of snaking at a later date, I definitely would not put the santee on it's back. Use two 1/8 bends (45 degree fittings) to offset the overflow away from the joist, and then turn the santee in it's intended orientation so that a drain cable from the overflow will pass through it.
