I can see the appeal of this but strictly speaking prefer to simply cut out the foam SQUARE and PLUM. Then cut properly sized foam squares, also SQUARE and PLUM, to snuggly shim the servo into place. This has worked great for me. In extreme circumstances, I've actually cut out a the foam area entirely and glued in a fresh piece of foam as replacement. Then cut a *new* servo hole in the fresh plug of foam. I've replaced entire noses on combat planes just this way. No problem with a band saw!
