Is there still a decent chance to get selected to be an aviation warrant if I need an age waiver and waiver for active federal service (AFS)?

I need to renew my flight physical and obtain a letter of recommendation from a warrant officer. I'm currently deployed to a location that doesn't offer initial flight physicals and I have until November before I will require an age waiver. I already need a waiver for active federal service. I really want to pursue this, but at the same time I don't want to waste my time if there's no chance of getting in. Thanks.
