Although your reasoning is solid, I think your pairings are off - Stuart has proven most effective as a number 3-4 d-man and Kronwall is the heir apparent, so I think he should play along with Lids for at least a full year and the same dynamic applies:
Glad to hear he is coming back. Now all we need is for someone to PLEASE, convince Babcock to pair him with STUART. With that pair you pick your poison entering the Wing's zone. Lidstrom (the wizard) ya can't make a play against or Stuart(the bull) who will knock you on your ass.
