That depends. I would never make such a rebid with a hand in my opening 1NT range. I play a weak NT, so I guess it is more dangerous as I would be overstating my hand and we could end up in a poor game, but anyway I have never considered it.
What do you bid instead? 2♥, even though you don't have the appropriate shape for a reverse?
This is what I meant by this being a problem for many systems -- something has to be distorted.
