Shrouds lift deck ....

[Marieholm26]

Thanks to this forum and Thanks to Brion where I received excellent directions on how to solve some problems of rigging.
I have a problem: My deck lift where the upper shrouds are anchored in the chainplates.
It 'is a common problem in Folkboats... I'm trying to solve the problem without upsetting the boat just redone.
I found this solution (See photos) on the internet and seem for me a good idea, but i'm not sure. what do you think?
The only place for the anchor is on the bulkhead and the cable attached works only diagonally....
I need some advice...
THanks a lot for any help!
