100% fair. Linking a portfolio on your CV/resume should be standard practice for a designer. As for efficiency, it depends on how you define it. You will probably find your candidate pool is now relatively limited and it may take you a bit longer to find the right designer but it will certainly filter out those that just aren't destined to be the right fit anyway. There is only one person that knows what the absolute perfect candidate for the job looks like and thats you. If that picture of perfection involves having an accessible online portfolio then so be it.
