I see that you were looking into finding pork substitutes sometime back and I was wondering if you found what you were looking for. I have been looking for exactly this for some time now as I am planning to open a restaurant soon and realize that many dishes require ingredients such as bacon/pancetta .
So far (as far as bacon goes) I founds substitutes like lamb, turkey, or beef bacon. I'm not sure how they rank against pork bacon as I do not eat pork myself, but for what it's worth I liked them although my opinion may be moot.
As far as ham goes I have tried turkey ham but am not really sure how they can make it even remotely like pork ham.
The good thing is that certain ingredients (particularly cured/dry aged meats) like salami, for example, although may be most commonly made from pork, also have beef, lamb or other non-pork versions.
Currently, I am still looking for substitutes/variations of pork products including bacon/pancetta, capicola, pepperoni, etc.
I guess my biggest issue is that having never tried pork products, I have nothing to judge against so I must rely heavily on the opinion of others who have had it.
