Do you plan to keep the larger tank as FOWLR? If so, either approach will probably work.

You can still use LR and a skimmer even with the wet/dry. Some people describe the wet/dry as a nitrate factory which, by itself, it probably is. All of the nitrates produced by the W/D would, however, also be produced by LR as well...and then consumed by different bacteris in/on the LR. LR will still process nitrates, no matter how the nitrates were generated.

Even so, most of the fish are not particularly sensitive to nitrates anyway. (you just have to worry about algae thriving on the nitrates...)

Keep the skimmer or upgrade it or even add a second if you have space--get rid of the proteins before they break down. Does the big W/D still leave room in the stand for a second sump? Perhaps you can add another, connect them with big bulkhead fittings and get extra skimming and even a refuge under that big boy!
