I am thinking that it would be possible to remove pill coatings using an acidic dh20,

This should remove the watersoluable coating, and leave the ephi un touched.

any thoughts

yeah,,if you use an acidic dnh2o then it may turn the psuedo into a freebase,,which means you will have to change your extraction solvent,,,ive noticed some coatings will not break down but are filtered on psuedo extraction ,,,,,you could try a mini hot acetone wash to see if it removes the coating,it does for some of them
