Those all sound fascinating, and I look forward to what you choose to share from your experiments. The agalmata sound like the thing I might be able to work in the soonest, and are synchronous with my plans to look more into Neoplatonism for pointers on practical polytheistic worship, so I'll have to look into the sources you and hwistle mention.

Not for JMG, obviously, but for anyone interested, Tom Rowsell has a video/podcast review of Gregory Shaw's Theurgy and the Soul, which includes some of his thoughts on how to apply Iamblichus's ideas on different beliefs and practices for different cultures to Heathenry: https://www.youtube.com/watch?v=u6NVzuXkdHM
