My initial reaction was to say Honor-ah. It's okay IMO. I actually like Honore (Honor-ee), the street name you mention, better! :)
I have a "thing" about names that will get mispronounced a lot... my DD's name is one of them and I kind of wish I thought it about it more before choosing it (even though I think the proper way to say it is beautiful). I think Honora would be one of those constantly being mispronounced names.
