Makes complete sense, Paul.
TAG metal parts may work. I think some metal pieces are a bit 'chunkier' and this might be an issue. Avanpost are very 'true scale' so no oversized hands etc. Muskets are the biggest thing I've found that are difficult to blend in with other manufacturers - I haven't used any Avanpost musketeers as the muskets are probably true scale but then look very different to everyone else's.
