I second the idea of a Vandoren Java A45, although I'm surprised a Jody Jazz HR 6 can't do what you want. In fact, it can do what you want, I have one right here on trial (not sure if it's the same, this one is called a Savannah model) and it's a very fine mouthpiece.
While playing lead alto professionally I used a meyer 6M, and at various times I tried larger tips and different pieces, e.g. Lawton, Barone and Guardala, but I always came back to that 6M because the wider tips didn't actually give me any more projection than putting the same amount of extra effort that those mouthpieces required into my embouchure and breath support with the 6M.
Plus, I found the intonation to always be better with the 6M. So my first recommendation is to stick with the 6 Jody and work at your technique so that it gives you what you want.
If you want a different mouthpiece (and most of us get those urges), then I would suggest you try them out for yourself, it works much better than asking for recommendations from people on the internet
