If not, I have a in-tank isolation box that can potentially be a in-tank refugium.Also, I have a canister filter which has carbon and bio media in it, should I get a skimmer? Any advice is appreciated. Thanks!

I will answer some of your questions. However, without knowing more about your tank and what is your dream for it, it is hard to offer advice.
Are you using GAC. I would recommend using it continually, no matter what method you go with. GAC is compatiable with all methods but cryptic zone sponges, both compete for DOC (dissolved organic carbon). While I circulate thru canister filter with GAC in it, I only change GAC when bio indicators like GHA indicate a need.
If this is a temporary solution, then I would advise one thing.
If you are interested in a mixed garden lagoon tank, then I would recommend two different growth rate macros. Fast growth rate like Caulerpa Prolifera, looks like oar grass, provides a nice green undulating wave. Do not let it’s holdfast get on your rock. Now Grape Caulerpa holdfast are easily removed of all bits. An added benefit of Grape Caulerpa is it makes a good snack for nutrient export. I dip it in fresh ice water to remove salt and most importantly enhance crispness. I eat this as a garnish with ceviche or on its own with sesame seed oil, sweet cooking rice wine, soy sauce and lime juice. For decorative macro I like Red Grapes. With red and green colors you would start out with a Christmas theme.
