Happy day Bob,
I recall that the IRS doesn't do K1 matching very well, if at all. So what I have done the past two years is I split the K1 into two pieces for entry onto his 1040. Using the ratio of workshop to consulting, I split the K1 and the 199A info. After I wrote my question, I posited the idea that since the costs are so low, it would be better for him to start a 2nd entity. Even with the related party ownership rules, I think it can be cracked and packed.
