We didn't realise we could share skills without sharing trauma before attempting this so instead Kit is going to split again leaving 'driving skills fragment' at the front for us and Kate leaving 'cooking/cleaning and social skills fragment' at the front... (Hopefully this will help us organise ourselves better to be more productive as we're quite disorganised and not much gets done regarding sorting/decluttering!) These will then make up 'Levi' with 'Jay' and the fragment Bobby left.
TS has also just decided she will leave a fragment at the front but wants to be able to return inside too and then just re-blend with her fragment when she wants to front with Kate or LS.
This seems to allow us to make a smoother transition between alters than a 'sudden switch' and then all share the same skills (Thanks to ArbreMonde for that idea!

We've decided 'Total fusion' (ie down to 'one') is not for us, but we still want to work towards being able to be more efficient when we do want to work together to get stuff done!
LS wants us to stay living as 'her little family' without people disappearing ..she doesn't mind us coming outside 'to work' but as long as she can still visit or we go back in to visit her! She has clearly expressed that she wishes to remain 6! ..she wants Jody to stay 6 with her ..(Jody's a changeling so thats possible) and lil P to stay 4..or 5 (max..he's a changeling too too so a 'human age' will not affect his changeling abilities) she insists she still has to be his BIG sister!

and although she misses Bobby. ..(who is now preferring 'adult mode').. B. can actually age slide to any age they choose, so can go down to 10 to visit her inside for them just to have a play for 'old times sake' in the holodecks if they want to! ..or to play out here on the switch together 'as kids'...we will set aside Saturday or Sunday afternoons for them to spend time together.
Thanks for your advices
Levi
