Do you know their upk numbers?
If so, then just replace all the numbers within the upk using Hex Editor, for example where it says 020033_LynM or 020033_LynM_Physics, replace the numbers with something random like 123456_LynM and 123456_LynM_Physics. This worked for me at least, but I was using a bit older set of ears and tails, but it should work for everything.
*edit* of course, copy paste the upk first into the mod folder, edit after ^-^ this way you don't lose the original
