Some sort of complex brushwork can do this, it'd be easier the less dense (read: the less links in the chain) that you make it. If you use square links, which aren't all that uncommon, you could easily make a 4 brush link and copy and paste it, rotating, to make the entire chain. Select them all and tie to entity func_detail.
This might be a pain but I can see it having decent results if you make the chains large enough.
