I don't think I'd want any where the Hemlock might have rubbed off on them. Can the hemlock toxins spread through the roots from one plant to another? I wouldn't think so, but I could very well be wrong!
The hemlock is best removed, roots and all, there is no part of this plant that isn't poisonous and making any type of
compost or other soil additive with it will only put the toxins back into the soil, where they will be taken in by other plants.
The toxins do not "leak" out of the roots of the hemlock, so growing other plants near these doesn't cause problems for the other plants.
Hemlock used to be used as a "hedge row", even in ancient Greece this was the common usage of hemlock bushes, along with the use as a poison.
The thistle makes good compost material or can be used as a mulch layer, it is a mineral mining plant so using it for either will put those pulled up minerals into the topsoil layer.
Both of these bushes are fungal dependent, so if you were to let them grow, the hyphae network will develop fairly quickly, then when you pull the hemlock that network of hyphae will remain for the most part and it will connect again as the hyphae regrowth occurs.
