Hi done a few bits like that up in the lakes,
First is properly the same church beck route you already have info on, however its just north west of Coniston more of a cannoning route, it starts 54.372796, -3.087258 next to waterfall

You can use either path from Coniston to get there, then work your way back down church beck, many good jumps and slides but without a guide I would check all water levels before hand, it did it last may water levels were fine.
The other good one is either a ghyll scramble or canyon depending on which way round you do it in Seathwaite again at the bottom of the waterfall 54.499330, -3.185073

This does have bolt in place but I did this couple of years ago so not sure as to its workability now,
Not sure if any of the above info is useful but saw your post and thought I better chip in
Enjoy
