DISCLAIMER: I did not make this! It's just so awesome that I have to share it.
Google Translate version
Original JP version
This site provides a very powerful Moghancement Calculator that lets you specify furnishings you want, as well as up to three Moghancements. It will provide a complete plan, including which furnishings are to be removed to switch Moghancements.
I asked some JP-fluent friends to help translate and explain the functions, so I'll go over them here, using the terms from the Google Translate version.
Support Effect: The Moghancements you want. Most of them are reasonably self explanatory. "Great" craft skills mean Moglifications instead of Moghancement. "Isao Isao Up" is a poor translation and means Mog:Campaign.
Attribute's minimum: Minimum elemental strength desired, if you care about that.
Number of used furniture/Maximum number of storage: Maximum number of furnishings to use and the maximum allowed Storage (in case you want less than 80 for some reason.)
Tick boxes: Check a box to exclude furnishings of that type. Options include: Guild crafting furniture (unless specifically needed for selected Moghancement), national flags, mannequins, Ex items from quests/chocobo-related activities, Ex furnishings bought at airship shops, holiday furnishings.
The big list: If a number is filled in for a particular furnishing, it will use that furnishing in that quantity in the design. You can specify 0 (I hate nine-drawer almirahs, so I exclude them from my designs, for instance.) Good way to make sure to include cherished items, too.
Once it calculates, it displays one or more list of furnishings. There's a link above each list that takes you to a page where it shows pictures and descriptions of all the furnishings that you need. If you're doing multiple Moghancements, it marks them as [A][B][C]. Some furnishings will also be marked with those letters. To get Moghancement [A], remove all furnishings marked with [A], etc.
This just saved me an hour's worth of deliberation and scratch work. It's very current - it even has the Egg Buffet and the new Noble's Beds/Storm Lamps included, as well as the Mannequin updates. I hope it helps you guys!
