I was watching an old episode of a brewing podcast, maybe Basic Brewing & they did test brews boiling the hops first for about half of the boil, then adding malt at the end. I can't remember the specifics of why they did it but I don't think you will have any problems. As long as the malt boiled for 15+ minutes, it's sanitized & it might have some unique hop flavors.
