Anchorage to top of brick masonry wall

[JAE]

Trying to attach a series of small stub columns onto the top of an existing, and fairly old, multy-wythe brick wall.
I think the wall is 3 or 4 wythes thick. Probably 80 to 100 years old.

There is tension uplift on the stub columns - probably 1000 to 2000 lbs but we have some control on this to minimize.

Hilti and others have data on anchors into the face of the wall but not the top of the wall. We called them and they confirmed that there is no testing for it.

One thought was to have the contractor drill or cut down into the top of the wall and install grouted pockets of grout with embedded/headed anchors.
The idea being that the grout plug would engage the brick around it and if we are deep enough we can then lock in the weight of the surrounding brick to provide the necessary hold-down weight.

A previous thread on this covered this similar topic: thread194-368784

Any thoughts on an approach? We are reluctant to cut down the side of the wall (into occupied tenant spaces) and fasten to the sides.
