No, I would like RK sit out as long as she can until she is 100% ready to go. If she does play, I would have her to come off of the bench and play sparingly. I would not want to disrupt the rhythm this team has right now with EA starting and playing.
I see what you're saying, however if you look at how Carolina has been defended by Texas, ND and UCLA it was to take away the point guard and totally disrupt the guard play in General. You'll need as many guards as possible in Games like that. HH of ND will disrupt your offense herself. TX used their best and biggest player on UNC guards/Madison Booker. UCLA has the back line to punish drives to the basket. If you come up empty, not good and your biggs may be in foul trouble by that time.
So,yes the chemistry is good but,if you don't have an elite guard like HH to make up for mistakes. Their plan is to take away the PG/Ball handing guard against us by elite teams. At some point you'll need another guard for the Top 4-6 teams in the country. Maybe not against Louisville but definitely against ND if they make it.
I do agree with your take on how to bring Kelly back into the lineup.
