The risers certainly look very nice and seem to be a great alternative.Since you have already spent the money on Teak I would highly recommend against sealing it with any form of epoxy or varnish. The reason Teak wood is used is because of it's natural oily properties and this oil resists rot all by itself. Renewing the oil occasionally is the key to maintaining nice teak.
The factory risers under my 1974 winged console are 36 years old right now and have been seriously neglected. I have them out now and the teak is in excellent condition except for the mounting holes being elongated. I contacted BW and asked what the factory recommends for this wood. Interlux Teak Oil and give it as much as it will take was the answer.
I figure if the teak has made it 36 years and is still good then that is good enough for me. Additionally, when you completely seal teak you take away it's ability to breath and this could cause premature decomposition. The natural oil in the wood is the key to it's longevity in a marine environment. Give it a drink every now and then and it will out last you.
