I would suggest you to hang in there with the spousal sponsorship. Its been 5 months since your file was transferred to Islamabad and the average time for spousal sponsorship(for wife) is about 15 months avg, unless the cases is very weak i.e. phone nikkah only and minimal pictures. I would think that you have 10 more months to go. Thus, in my opinion there is no need to apply for her as a skilled labour.
It might even create problems in your spousal case when they notice that she already has an application under spousal sponsorship and she is still trying hard to immigrate to Canada making it look like that she married you only for immigration and the marriage is fraudlent.
