Hanger or recommendations for steel hanger for deck beam

I am building a deck. One of the beams (beam 1 in sketch) is a 20′ x 5-1/4" PSL beam. The beam is sitting on a 6×6 concrete post with a carport post saddle on one side. My plan is then to mount two steel L brackets with threaded bar nutted and epoxied into a 8" concrete wall of the house. I’d place one at mid span and one at the other end.

The beam will sit 1" from the concrete wall. I’d like to bolt the L to the concrete and then lag screw from the bottom of the L up into the beam. Is there existing hardware that would work for this or do I just need to get something made? If I do get something made what thickness should I go for? I was thinking 1/4" HDG 6"H x 6.25" shelf for the legs and maybe 6" for the width.

I don’t want to do posts and more footings and I think this approach is better than bolting the PSL through a 1" piece of ply and directly to the concrete. If the beam ever rots and it is just attached to the two Ls it would be quite easy to replace. If it is bolted to the concrete everywhere I think it will be quite a bit more challenging. I also think that drill all the holes and bolting the beam would be more work than just mounting the two steel Ls.
