If you really mean you've got 35mm from tile to brick, I'd just bung
filler in & redrill. The filler creates solid sides for your new hole,
which you can then fill as needed.

The 35mm is only where I measured it. The Victorians used the most
irregular bricks where they knew it was going to be plastered, and kept
the best one where on show.

My worry about simply filling the void is that the load will be taken by
the tile - unless it bonds well to the brick. As the plaster ain't up to
taking much load.

I met similar in my father's house in Edinburgh when putting hand rails.
The house was built of stone, so, much more irregular. I think I ended up
with 4 inch screws.
