Yes, but I said that you will not be in a position to judge wether it
is reasonable or not because you will be seeing the visual
representation instead of the logical one.

I'm not sure I understand what you are saying: Do you think that it is
possible for bidi-visual-to-logical to do the right thing?

Note that this implies understanding the difference between
"my BMW230" and "my 230BMW" and understanding the difference between
"my 123 CARS" and "my CARS 123".  I think that means that Emacs should
be able to understand the difference between BWM and CARS.  I don't
think we will be able to do this.
