I have to admit I have never grown rabbits foot ferns. I can't advise you there. That being said, I love to experiment and would try doing what you suggest just to see the results. Take a few cuttings and start them just in case the experiment goes south.
Cork not only looks great is makes the best mounting material I have ever used, and I use 10-12 different woods for mounting.
The only difference in the "standard" bifucatum and the 'Netherlands' (visually) is that the Netherlands grows a bit slower and does not get quite as large. Out of site is the fact that the Netherlands is more tolerant to heat, cold, and drought. It will more likely forgive you if you grow plants on the dry-side.
I have just started some Platycerium Mauna Loa, P. Mickey's Rainbow, and P. lemoinei (aka "Silver" and "French"). These are all rare and very different (and more beautiful in my humble opinion) than the bifurcatum. I look forward to seeing these pups develop on their mounts.
