Pinhole mounted in bodycap on EOS cameras

I am wondering if any of you more experienced people on the list can
help me with this minor challenge. I will like to mount a pinhole on a
bodycap and put it on one of my EOS bodies.
I have been searching the net and have found a lot of information for my
other pinholeprojects (4x5", 6x7) but not on this particular subject.

My questions are:

How do I measure the distance from the filmplane til the pinhole?

What will the optimal pinholediameter be?

Will my built in exposure be able to measure the light and set a
"correct" exposure?

What else should I think of?

Regards
