One easy way to avoid de-normalizing weights would be to just calculate the averages separately by survey round and then look at the "trend" - meaning draw a line between the two points. Then you can just use the original survey weights, and you don't really lose much power (you are just implicitly allowing any covariates to have different effects at different points in time - if you are using covariates, which I don't see a real reason for if you just want to analyze simple trends over time).
