Xtracycle accessory compatibility

I’ve been riding a xtracycle free radical conversion of one type or another for 6 or 7 years now and we’re ready to move up to a purpose built bike. We’re looking at the Yuba sweet curry or the Xtracycle whatevertheycallit.

We already have a deck, panniers and a yepp maxi with the mounting kit for the Xtracycle. Will any of that work with the Yuba?

Thats gonna be a big deciding factor I think.
