The result will be that not all overhauls will have full expression regarding what is spawned from their lists.
So depending on which is loaded last will win - with BOSS as it is now and no userlist it will be Frans then WAC then TIE. So TIE will win out most of the time. WAC adds spawn points, so I"m not sure if TIE will mix with those.
Then the weapons of WAC will be underpowered with regard to the 'vanilla weapons' of TIE. I found that the answer http://www.gamesas.com/index.php?/topic/1210139-anti-scaling-mod-compatibility-issue-help/page__view__findpost__p__18103669 to be the best. In short I made a vanilla weapon stat patch to return weapon stats to vanilla levels. Then not use the TIE filter patch.
But to be clear I then combine with Duke Patrick mods that up weapon stats through scripts and adjust damage formula to be more deadly. But other mods do this to: Phitts Pighting Phixes, Kuertee Attribute damage, Deadly reflex, etc.
Also while they are not complete this guy has made a series of patches for combining WAC with other mods:http://shy.jsphr.net/upload/upload.php?search_keyword=ItemLootFix&word_match=free_word_match&act=search&view= There is a patch for Frans, but not TIE - I did ask him for a TIE patch though, so maybe someday soon.
I have a TIE+Frans load order - if I get it more stable then I will add in WAC too.
