Even if it was: do it. Making the calls you don't really want to make is something you can't learn early enough.
From my experience: it's fine and nobody will be annoyed unless you make it a habit to call them each day. It may simply show them that a) you listen to advice, b) you're flexible enough to discard old ideas, and c) you can execute quickly, which are all good things. It may also sound like you're just doing something to get funded, but that depends on your business, your pivot etc, I think.
