How about if I fill the 1/8" expansion joint between the sheets with sill gasket up to the top of the 3/4" plywood and fill the rest of the large gap with floor leveler compound like mapei planipatch? I was thinking fill just the space between sheets and lay gasket against tub but that's getting too complicated. This way I can run some of the patch under the tub edge for extra support.

I even updated the diagram! Sorry, couldn't get the colors of the thinset and kerdi-fix quite right. Otherwise sound reasonable?
