It's a ton of unpaid, volunteer work, if I want to be a high quality reviewer then it's at least a day (at least 3 thorough reads, taking notes, writing the review, reviewer discussions, post rebuttal, back-and-forth for journals). I am lucky and privileged that my employer counts this towards work time.
Only 20% papers get accepted in my domain.
Now if I had to spend a week on replicating a paper - and this is CS/graphics, where it's easy and "free" - I'd never volunteer to being a reviewer.
You'd need professional "replicators", but who will pay for them? And who will be them - you need experts, and if you are an expert, you don't want to merely replicate others people work full time, instead of working on your own innovation.
