No problem, I totally understand kits don't work exactly like mods

I'll keep an eye on the thread you mentioned.

Sorry i didn't see that post and it indeed answered some questions.

About my test, it ruined my install ... I guess i'll have to make a new one   Weidu couldn't manage to roll back and reinstall that much mods it ended with somme nice fireworks  

Now you can install as you wish, kits you have previously had to skip. This can be the TDD or RoT kit packs or
single kits from different mods.

This phrase in your guide (and your post) is a bit misleading. That's exactly what I wanted to do. But since i couldn't choose to simply add the kits, i crashed my install. At least the RoT kits can't be installed after the megamod.
I keep no grudge on anyone ... except me for not making any backup before trying some risky move   And with this new Installer it's so much easier to make un mega-installation, it's almost funny  

Would it be possible to make a list of all available kits (from the supported mods or selected mods) in the Big World Installer to choose from ? that would be awsome
