Plenty of reasons to be optimistic about those hires as producers.
1. Pascal has prior Bond cred, having worked on Casino Royale, Quantum of Solace, and Skyfall.
2. Heyman had a hand in producing Harry Potter, Paddington, and Wonka - which means the requisite Britishness won't be absent.
3. From what I understand, Pascal was the sole Sony executive who spoke out against Spectre's Blofeld twist (Brofeld) - one of the least popular storylines in recent years. This was revealed in Sony's hacked emails.
4. Barbie was a bonafide blockbuster - regardless of your thoughts on Barbie, if these producers can replicate such success, it's a good thing. We want Bond to stay mega-popular.
