If you had filled a 485, and then go for CP, then the 485 will be withdrawn, but since you don't have a 485 pending based on your 140, there will be no 485 to be witdrawn.
The 485 based on your wife's 140 cannot be withdrawn, because she didn't show interest in CP, you are showing interest in CP. I would suggest that you do AC-140 Consular Processing, and also let your wife's 485 be processed.
Talk to your attorney as to exactly what you can do. With AC140 you may be approved withing a year:
Here is the response to an email I had send to the Mumbai consulate regarding AC140:
I am cutting and pasting the email correspondance.

1. Yes
2. We also need copy of I-824.
3. After receiving the package, if accepted, we will create a case and we will do the necessary clearances/namechecks. It will take about 2 to three months to schedule an appointment after receiving the clearances.

Subject: Employment Base Consular Processing AC-140
Dear Sir or Madam,
I read on
http://mumbai.usconsulate.gov/wwwhimmi.html#empcases that I can qualify to transfer my pending Employment Based (EB) change-of-status application to Consular Processing to Mumbai consulate if I meet certain requirements. I do believe that I meet the conditions listed on the website, and so I was planning to have my attorney send you the following documents:
Copies of I-140 paperwork
Original I-797 Notice of Approval Form for I-140
Completed OF-169 and OF-230 part 1 forms
Email address and contact detail for my attorney
However, before my attorney does send you the package, I have few questions, and would appreciate if you can answer them.
1. If the consul decides not to entertain my application, then will they return my original I-797 Notice of Approval Form for I-140 back to my attorney?
2. If the consul decides to entertain my application, then within how many days, can I expect to be interviewed? I ask so that I can decide if making travel arrangements at that time is feasible for me or not.
3. I got the above list of documents from
http://mumbai.usconsulate.gov/wwwhimmi.html#empcases, are there any other documents required for the consul to make a decision to accept my case or not?
I would greatly appreciate if you can email me the answers back as soon as possible so that I can take the necessay steps.
