No, I think now it _is_ a comparatively simple way:

import tkinter as tk
from tkinter import ttk
from tkinter import font


def changefonts():
     for fontname in [f for f in font.names()
                      if font.nametofont(f).actual()["family"] ==
                      "Inconsolata"]:
         font.nametofont(fontname).config(
             family="Bitstream Vera Sans Mono")

def main():
     root = tk.Tk()
     changefonts()
     ###... build your gui
     root.mainloop()

if __name__ == "__main__":
     main()

This should work for all themes. It seems unnecessary on Windows and on
Linux problems with the fonts probably depend on the chosen desktop
manager.
