FWIW, I did a search "DXi hosts", thinking there may be a VST-Host-like application out there.
I had a few hits that looked promising, though whether the answers will work for you, obviously I couldn't say.

This page: How to Use DX Plug-Ins with VST-only DAWs was one such hit.

As an alternative, there are the various soundfonts out there for VSTs like the VSTSynthFont64 that comes bundled, but not installed, with BIAB. The manual gives how to install/use it.
