Patrick, It is possible to get the basic courses and Bareboat taken care of in one week, but with no previous sailing experience, this is unlikely. If you can get some small boat sailing in this summer and do some studying ahead of time, that may make all the difference.
I also got into cruising based on a background of kayaking and canoe expedition leadership. While these things may not help a lot with getting your bareboat certificate, I believe this background will likely be an enormous help in making you a proficient cruiser. The physical skills are different, but the the same problem solving ,awareness skills, and sense of responsibility you have developed as an expedition kayak
leader will help you problem solve and be comfortable cruising. I'm amazed how much similarity there is between these things. I even wear the same basic clothes on a canoe expedition for example that I do sailing. (But having a few extra changes of clothing
sure is nice!)
Another thing to consider, is you don't both need to get bareboat certified off the boat to go charter
a bareboat. If your wife gets re-certified and you have the basic courses and feel competent and confident, that may do it. The Moorings, is once company that will allow you to start your bareboat charter with a "friendly skipper" that you can take out for a while, but let off once he (or she) and you feel confident.
If you do this with ASA
, be sure you start your log book and your wife updates hers. It will help you when it comes time to charter.
All the best. Sounds like a great Honeymoon to me.
