two recipes, one replaces files of another

Good time of day, people!

I have two recipes for two cases:
recipe-brdRevA.bb
recipe-brdRevB.bb

both of them has one file:
/etc/myprog/c.conf

and two image definition files:
imgA.bb
imgB.bb

, that requires recipe-brdRevA.bb or recipe-brdRevB.bb indirectly by 
IMAGE_INSTALL += "myprog"

myprog.bb requires files from recipe-brdRevA or recipe-brdRevB, 
depending on image.

It's not a correct idea to add IMAGE_INSTALL += "recipe-brdRev<N>" into 
img<N>.bb explicitely.

How to create dependencies correctly?
I try to add
RPROVIDES_${PN} += "recipe-brd" in both recipe-brdRevA/B  and use 
PREFERRED_PROVIDER_recipe-brd = "..."
into imgA/B.bb without success.

Please, advice me.
