Well, you could do what I did just now and make a swatch trying the different approaches.

What I think I would do is to inc in the WS row as it says, keeping the k tbl and just using a backward loop increase when needed for the inc.
If you want to inc in either the knit or the purl I'd inc so that the purls are increased on the right side, they will recede and not be so noticeable.
