If so, could someone please comment on what changes (if any) need to be made? I've looked through other posts...just haven't found my exact application. Thanks.

Depends on the amount of shunted current. If shunting 50mA or more at 6v then I would definitely use larger heatsinks.

As for transformer size, you will be consuming less then 4VA, to 30VA is overkill. It will certainly work fine though.
