A DangerBird mod that will look something like this..
when you look at a naked DangerBird (bug net stuffed, over cover stuffed) you normally see two 'balls' at each gathered end, e.g. the stuffed bug net on one side and the stuff over cover on the other.
Someday in the future you'll see four 'balls', the same two 'balls' at each end and a 'ball' under on each side.
These new sets of 'balls' (I'm laughing writing that!) will be under the gathered end and each will contain half an under cover.
You put on your underquilt then deploy each 'under ball', i.e. half an undercover from each side.
The under cover halves (made of course in Momentum) will join each other in the middle and the amount over overlap will determine their depth.
You want the depth to be able to vary due to the thickness of the underquilt you've selected.....not as much overlap for a WB Winter Yeti or the LeighLo 5-50 (both rated to 0F); then again if using a TeWa summer UQ you want more over lap.
Now how the overlap is to be maintained ~valco tabs on one side and a velcro strip(s) on the other, I don't know; that will be up the the genius we know of as PapaSurf.
So Papa, want to make me another Dangerbird with balls! HA!
Now think of the colors!
The overcover in jade green.
The hammock body in chocolate.
The hoods (what I've been calling 'balls') in champaingne.
One half of the under cover in coyote, the other in jage green again.
DAMMMMMMMMMNNNNNN what a colorful bird!
Let me know when you get caught up PapaSmurf
