H-m-m..., no "quick-and-dirty" way to approximate VaR? "Must" build 200-and-something curves and "must" do full valuation?

The problem with netting the legs before computing for VaR is that you assume the rates to go in the same direction at the same magnitude.This is not the case since rates used for both legs of your IRS are different despite being picked from the same curve.Taking basis risk and yield curve twists... correlation needs to be estimated for the rates.

I would still like to try and find a way to get a sensible VaR estimate for a vanilla swap based solely on values provided by Bloomberg - without building/modeling anything. Any ideas in that sense would be highly appreciated.
