First up, stop talking to yourself in public. :D
Jokes aside, I think a better option is to combine two tables to one using either Power Query or Combine DAX function. You may also add a type column in source tables to distinguish tables. Then set up star schema (ie just connect the dimension tables to single fact) and use CALCULATE to filter your measures by either table values.
If you wish to retain both tables, you can use the excellent USERELATIONSHIP() to define which relationship should be used when defining the filter context for the measure.
