Usually if I meet resistance I backtrack and try something else sooner than later within the same sprint. You can usually feel if your codebase isn't flexing properly and the change is going against the grain. I don't think that is different whether you split up the work or do it in a single sprint. Personally I think you can see from the top down and get a better vision the longer you are working in something which helps with that specific problem.
