Yes , you can definitely do that , chances of getting spousal are 100 percent if your case is genuine and and also if your husband meets the criteria ,
I'm sorry to hear that , there is no harm in trying to apply visitor visa because it only takes 2 weeks max to process(even if it gets denied it will have no impact on the pr sponsorship ) , but make sure you get all the required documents and files , reasons to satisfy the visa officer that the visit is temporary , when he finally lands in canada you can move forward however you like.
