Kurt, Looking at the original TS-DOS with the code located at 3535H, the first routine there (3535H - 3563H) could be moved pretty easily to a different address with a "JMP 3564H" at the end. This routine is only called from one location in the original ROM (the JMP at address 0109H).
All of those bytes between 3535H and 3563H can be moved without needed to change any of them … put them anywhere and then simply JMP there instead of 3535H (plus change the JMP at 0109H). This would give you 46 bytes of additional space, and you said the overlap is only 36 bytes.
