I found two mods that look like good add-ons for Frostcrag. One is for Midas Magic (available here: http://www.tesnexus.com/downloads/file.php?id=15951 ) and the other is called Frostcrag Reborn (available here: http://www.frostcragreborn.com/downloads.html ). Is there a way to determine ahead of time if these mods can co-exist or if the are not compatible?
For what it's worth, I can not recommend Frostcrag Reborn enough if you're going to pick a Frostcrag mod. In addition to the intial "quest" to get the place and equip it, there are two more quests that are very challenging. The second of these is huge and has great benefits. But it's not just that... he did a great job with the entire thing. Architecture, design, atmosphere, etc... It is very well thought out and tons of fun. But, it also has a sticky point or two when installing, especially if you already had Frostcrag running in an existing save (Read te README very thoroughly). For that reason alone, I probably wouldn't try running these two Frostcrag mods side-by-side. Further, Indefiance's Frostcrag has a nice Cobl lab (if you run Cobl)... no, it's not Midas' equipment, but it is a very nice alchemy lab with plenty of Cobl storage for your ingredients, potions and scrolls.
So there's my $0.02. I love Midas' shop, and I love Frostcrag Reborn. I am currently running both in my build. But I don't know that jamming them together is going to get you the results you desire. YMMV.
