If your responsibilities increase, and you're charged with more risk of failure (larger projects, more $$$ at stake to the company), then yes, you deserve more pay. You're earning it.
It's perfectly reasonable to ask for more money every pay period OR if you trust them, take it as future raise or bonus (say at end of the year).
You can also ask to have some metrics that will generate a salary commisurate with the job that determine your final end of year pay. e.g. productivity, successful launch etc...
If you determine those firm metrics up front and you hit those targets, you get a bonus, negotiated up front.
In that scenario, they can mitigate their risk that you might not perform in the 'higher' role.
Most, if not all, business people expect some pushback and a negotiation. It's not only commonplace, it's a sign of mutual respect.
Don't be afraid to say "Yes I can do that, but I will need X to make that happen"
