The point of Aurelien's work is to create a set of plugins that can be interconnected together in arbitrary ways. Those connections consist of two types of data: audio and control voltage. The control voltage part is important.
VST has no concept of "control voltage". Even if you find a host that allows arbitrary connections between plugins, it will not have any way to support control voltage data connections.
This will completely break almost every idea at the heart of AMS and Aurelien's LV2 plugins.
VST, like most plugin APIs, only really knows about audio and MIDI. AMS does not fit into that paradigm, in the same way that no self-respecting hardware modular synthesizer lets you patch MIDI from module. They may support MIDI I/O, but the main data that flows around between modules is control voltage.
